Some people describe generalised anxiety as having several browser tabs permanently open in their mind. Work, health, money, relationships, children, decisions still to be made, something that might go wrong tomorrow, or even a conversation that has not happened yet. As soon as one concern settles, another takes its place.
Worrying from time to time is part of being human. The difficulty begins when worry becomes hard to control, takes up too much mental space, produces physical tension and begins to interfere with sleep, decision-making, relationships or the ability to enjoy what is happening now.
This guide explains what generalised anxiety disorder (GAD) is, some of the processes that can keep it going, how psychological treatment may work and what you can begin noticing in your own day-to-day life. The aim is not to help you diagnose yourself, but to help you understand the problem more clearly.
What is generalised anxiety disorder?
Generalised anxiety disorder is characterised by excessive and persistent worry across different areas of life. Unlike a fear linked to one specific situation, the focus of worry often moves from one subject to another.
Someone might spend the morning worrying about a mistake at work, the afternoon thinking that a family member could become ill, and the evening repeatedly questioning whether they made the right financial decision.
What matters is not simply what the person worries about, but how difficult it becomes to stop the process once it has started.
When assessing GAD in adults, clinicians consider factors including whether anxiety and worry have persisted over a period of months, whether the worry is difficult to control and how significantly it is affecting everyday life.
Other symptoms may include restlessness, muscle tension, irritability, tiredness, difficulty concentrating and disrupted sleep.
Normal worry or generalised anxiety?
The difference is not whether someone worries. Everybody anticipates problems sometimes. The distinction is more often found in the intensity, frequency, difficulty switching off and impact on everyday life.
Everyday worry
It is usually connected to a specific problem, can lead to useful action when a solution is available and often reduces once the situation has been dealt with.
Worry associated with GAD
It can continually generate hypothetical scenarios, spread across many areas of life and remain active even when there is nothing that can actually be solved at that moment.
One particularly useful question is: “Am I solving a problem, or am I trying to obtain certainty that I simply cannot have right now?”
This distinction matters. Working on a real, solvable problem can be helpful. Trying to eliminate every uncertainty about the future can become an endless task.
Why does the mind keep worrying?
Worry is not usually maintained because somebody wants to suffer. It often continues because, in the short term, it appears to serve a purpose.
Thinking through possibilities again and again can create the impression that we are preparing ourselves, preventing something bad or maintaining control. The problem is that any relief tends to be temporary.
Uncertainty appears: “What if my manager tells me tomorrow that something has gone wrong?”
Your mind tries to create certainty: you replay conversations, possibilities and possible outcomes.
You look for more reassurance: you ask someone, check a message again, review what you did or simply keep thinking.
You feel some short-term relief. Your brain begins to learn that checking or reassurance seemed necessary in order to feel better.
The next doubt starts the cycle again. Over time, it may become increasingly difficult to tolerate “I don't know”.
Intolerance of uncertainty: an important part of GAD
Many people with generalised anxiety are not only afraid that something negative could happen. They can also find it particularly difficult not to know for certain what will happen.
For example:
- “I won't be able to relax until I have my medical results.”
- “I need to know that my partner isn't annoyed with me.”
- “Before I decide, I need to be completely certain that it is the right choice.”
- “If I don't think through everything that could go wrong, I'll be unprepared.”
The difficulty is that life offers very few absolute guarantees. The harder we try to obtain them, the more closely we may begin monitoring every possible sign of uncertainty.
Part of treatment may therefore involve learning not how to find perfect certainty, but how to gradually increase your ability to act even when a reasonable degree of uncertainty remains.
Behaviours that help briefly but may keep anxiety going
Some coping strategies make perfect sense and can feel helpful in the moment. When they become repetitive, however, they may prevent the brain from discovering that uncertainty can also be tolerated.
- Repeatedly asking other people whether everything will be all right.
- Frequently checking emails, messages, symptoms or information.
- Spending hours online looking for an explanation that removes every doubt.
- Replaying conversations to find out whether you said something wrong.
- Delaying decisions until you feel a level of certainty that never quite arrives.
- Avoiding news, places, tasks or conversations mainly to avoid feeling anxious.
- Planning every detail in an attempt to eliminate any possibility of surprise.
This does not mean that checking something once is pathological or that asking for support is wrong.
What matters clinically is the function and frequency: what you do, what immediate relief it provides and what happens afterwards.
How generalised anxiety disorder is assessed
Good treatment begins with a good assessment. Not every period of intense worry is GAD, and physical symptoms should not automatically be assumed to be caused by anxiety.
A psychological assessment may explore how and when the problem began, what tends to trigger worry, your main areas of concern, avoidance, sleep, substance use, previous difficulties, work or academic functioning, relationships and other symptoms that may be present.
It may also be important to consider panic attacks, depressive symptoms, obsessive-compulsive difficulties, trauma-related symptoms or other conditions that could require a different formulation or treatment plan.
Brief tools such as Ocnos's online GAD-7 anxiety questionnaire can provide an initial indication of how frequently certain symptoms are occurring, but they do not replace a professional assessment and cannot establish a diagnosis on their own.
What treatments work for generalised anxiety disorder?
Research supports several psychological approaches, but cognitive behavioural therapy (CBT) is one of the treatments with the strongest evidence for adults with GAD.
A systematic review and network meta-analysis published in JAMA Psychiatry, including 65 randomised clinical trials and 5,048 participants, found benefits for CBT and third-wave CBT approaches compared with treatment as usual.
At follow-up, CBT was the psychological intervention that most consistently maintained an advantage over treatment as usual.
NICE guidance also includes CBT among the recommended high-intensity psychological interventions for generalised anxiety disorder.
What actually happens in CBT?
Cognitive behavioural therapy does not mean simply replacing negative thoughts with positive ones.
Depending on the person's individual formulation, treatment may involve:
- understanding your own cycle of worry and anxiety;
- distinguishing real problems from hypothetical worries;
- examining beliefs about the usefulness or danger of worrying;
- reducing avoidance and excessive reassurance-seeking;
- working on intolerance of uncertainty;
- developing problem-solving skills where a genuine solvable problem exists;
- learning different ways of responding to thoughts and physical sensations;
- returning to meaningful activities that anxiety has gradually pushed aside;
- developing a plan for future periods of stress or possible relapse.
What might treatment look like step by step?
There is no single protocol that should be delivered in exactly the same way to every person.
Responsible psychological treatment is adapted to the person's history, needs, preferences and specific difficulties.
Assessment. Understanding what is happening, when worry occurs, what triggers it and how it is affecting your life.
Shared formulation. You and your psychologist build a clear explanation of the processes that may be keeping the problem going.
Specific goals. Rather than simply “feel less anxious”, goals might include sleeping better, making decisions without repeated checking or returning to activities that anxiety has restricted.
Therapeutic work. Cognitive, behavioural and emotional skills are selected according to the processes identified in your assessment.
Applying the learning to everyday life. An important part of therapy happens outside the consulting room as new responses are practised in real situations.
Relapse prevention. You learn to recognise early warning signs and respond before older patterns regain their previous strength.
Practical exercises to begin observing your anxiety
The following exercises are not a substitute for psychological treatment, but they can help you notice some of the patterns involved.
Their purpose is not to make anxiety disappear immediately.
Real problem or hypothetical worry?
When a worry appears, briefly write down what you are worried about and ask: “Is there something specific I can do about this now?”
If the answer is yes, identify the next small and realistic action.
If the answer is no and your concern depends on something that might happen, notice whether you are trying to mentally solve a situation that does not actually exist yet.
For example, “What if I lose my job in six months?” cannot usually be solved by thinking about it for two hours tonight. “I need to send an important proposal tomorrow”, on the other hand, gives you something concrete to act on.
Notice your reassurance-seeking
For a few days, make a brief note whenever you try to reduce uncertainty through checking, asking for reassurance or searching for information.
- What doubt appeared?
- What did you do to feel safer?
- How much relief did it give you?
- How long was it before another doubt appeared?
The purpose is not to forbid yourself from asking for help. It is to discover whether particular behaviours are genuinely solving a problem or simply feeding a cycle of reassurance.
Practise small amounts of uncertainty
Deliberately choosing small situations in which you do not obtain immediate certainty can help you discover that you may be able to tolerate more uncertainty than anxiety predicts.
This might mean sending a routine message without rereading it five times, making an everyday decision without asking several people for their opinion, or waiting for a short period before carrying out a habitual check.
Start with manageable situations. The aim is not to behave irresponsibly, but to reduce checking that is no longer genuinely necessary.
Set aside a time for worry
Some people find it useful to note a worry when it appears and decide to return to it at a specific time later in the day, rather than immediately entering into a long chain of worrying.
This is not about suppressing thoughts. It is an opportunity to discover whether every thought genuinely requires an immediate response simply because it appeared.
Breathing, mindfulness and relaxation: what role do they play?
Breathing exercises, mindfulness and relaxation can be useful for learning to observe sensations, reducing physiological arousal and reconnecting with the present moment.
There is, however, an important difference between using these techniques as regulation skills and turning them into another way of checking whether anxiety has completely disappeared.
If someone begins thinking, “I cannot continue until I get rid of this feeling”, even a relaxation technique can inadvertently become part of the same control cycle.
If you would like to explore this further, you can read our guide to what mindfulness is and how it is used in psychology or use Ocnos's guided grounding audio .
Does generalised anxiety disorder require medication?
Not necessarily. Many people receive psychological treatment without taking medication.
In other situations, medication may be worth considering, particularly when symptoms are severe, everyday functioning is significantly affected or other clinical difficulties are also present.
Decisions about medication should be made with an appropriately qualified doctor or psychiatrist after assessing the individual's circumstances.
Clinical guidelines such as NICE include certain antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), among the pharmacological options for GAD.
Benzodiazepines, by contrast, are not generally considered a long-term treatment for generalised anxiety and require particular caution, including because of the risks of tolerance and dependence.
Psychological therapy and medication are not necessarily competing choices. In some situations, coordination between professionals may be helpful.
You can read more in our guide Psychologist or psychiatrist? When you may not have to choose .
How long does treatment take?
There is no number of sessions that can be promised in advance for every person.
Duration depends on factors including the severity and duration of the problem, whether other difficulties are present, your therapeutic goals, the pace of the work and your individual response to treatment.
Some structured CBT protocols are delivered over a limited number of sessions, but turning that figure into a guarantee for every patient would not be clinically responsible.
What matters is having a treatment plan that makes sense, goals that can be reviewed and regular consideration of whether therapy is producing meaningful change.
Can online therapy help with GAD?
Yes. Online therapy can be a valid option for some people.
Clinical trials have found positive outcomes from cognitive behavioural treatment for GAD delivered through videoconferencing.
This does not mean that online therapy is automatically the best option for everybody.
The choice between in-person and online therapy should take account of personal preferences, privacy, circumstances, clinical complexity and the quality of the intervention being offered.
When should you consider asking for professional help?
You do not have to wait until anxiety feels unbearable.
It may be worth seeking an assessment when worry:
- is difficult to control and occupies a significant part of your day;
- affects your sleep, concentration or performance;
- causes frequent physical tension;
- leads you to avoid more and more situations;
- creates repeated checking or reassurance-seeking;
- interferes with relationships or family life;
- causes you to make important decisions mainly to reduce anxiety;
- makes it difficult to enjoy life even when things are objectively going well.
An assessment can also be useful when you are not sure whether what you are experiencing is actually generalised anxiety.
Symptoms that look similar can have different explanations, and understanding those differences helps determine what form of support is most appropriate.
What can you expect from a first appointment?
A first appointment should not feel like an interrogation or a race to give you a label.
Its purpose is to understand what you are experiencing and what you need.
At Ocnos, we usually explore how the problem began, which situations make it worse, what you do when worry appears, what you have already tried and what you would like to change.
From there, we can develop an initial psychological formulation and agree with you what the next steps might be.
Our psychology clinic is based in Palmones, in the Campo de Gibraltar, and we also provide online appointments.

Frequently asked questions about generalised anxiety disorder
Does worrying a lot mean I have GAD?
No. Worrying intensely during a difficult period does not automatically mean that you have generalised anxiety disorder. An assessment considers factors such as duration, intensity, difficulty controlling the worry, associated symptoms, impact on everyday life and other possible explanations.
Can I still improve if I have been anxious for years?
Yes. A pattern having existed for a long time does not mean it cannot change. Research shows that psychological treatments such as CBT can significantly reduce symptoms of GAD. The pace of change, individual response and treatment goals vary from person to person and cannot be guaranteed in advance.
Do I have to stop worrying in order to get better?
No. The goal is not usually to create a mind that never worries. A more realistic aim is to learn the difference between useful problem-solving and worry that has become a repetitive loop, to respond differently to uncertainty and to prevent anxiety from continually making decisions for you.
Can the GAD-7 diagnose generalised anxiety disorder?
No. The GAD-7 is a brief screening and monitoring questionnaire. It can indicate that symptoms may be worth exploring further, but it does not replace a clinical assessment and cannot establish a diagnosis by itself.
Will I need medication?
Not necessarily. Many people receive psychological treatment without medication. In other cases, it may be useful for a doctor or psychiatrist to consider whether medication should form part of the overall treatment plan.
How many therapy sessions will I need?
There is no universal number. Treatment length depends on the individual's situation, goals, other difficulties that may be present, how long the problem has existed and how they respond to therapy. Reviewing progress regularly is more useful than promising a fixed number of sessions.
If worry is taking up too much space
You do not need to decide whether your anxiety is “serious enough” before asking for help.
An initial assessment can help you understand what is happening and what your options are.
At Ocnos Psychology Clinic, we work with people experiencing anxiety, persistent worry and difficulties related to fear and uncertainty, both in person in Palmones and online.
