CBT for anxiety: how does it work?

How does anxiety work?

Anxiety is an anticipatory response to a possible threat. It can help us prepare. It becomes more difficult when it occurs frequently, feels hard to settle or restricts everyday life.

A common sequence is: situation → interpretation → anxiety → protective or avoidant behaviour → short-term relief → anxiety may be maintained. This is a useful framework, not a single explanation for every difficulty.

For example, you are expected to speak in a meeting. You think, “I’ll lose my words and everyone will think I’m incompetent.” Your heart speeds up, you feel tense and you decide not to speak. Relief comes quickly. But you have not had the opportunity to discover what would actually have happened or to experience your ability to get through it. The next meeting may then feel just as threatening.

What does CBT aim to do?

The aim is not to remove all anxiety or make you indifferent to what happens in your life. It is to understand the mechanisms that leave you feeling stuck and gradually change some responses, allowing more freedom in your choices.

The work begins with specific situations: what you anticipate, how you feel and what you do to protect yourself. Goals are developed with you, taking account of your actual difficulties and circumstances.

Working with thoughts

Automatic thoughts are the words or images that appear quickly: “I won’t cope”, “Something bad is going to happen”, or “If I make a mistake, I’ll be rejected.” They may feel self-evident without being established facts.

Catastrophic predictions focus on the most worrying outcome. Some interpretations also draw on broader beliefs, such as feeling that you must control everything or never disappoint anyone.

The work involves stepping back and examining these thoughts: what supports them? What information is missing? What other interpretations are possible? This is part of what is known as cognitive restructuring. It is not about forcing yourself to think positively. It is about seeking a more balanced and useful understanding without denying real difficulties.

Working with behaviour

Avoiding a place, leaving a situation, checking a message repeatedly or continually asking for confirmation can bring relief. These reactions are understandable: when anxiety rises, we naturally look for ways to reduce it.

When they become habitual, however, they may prevent you from discovering that a situation is sometimes less dangerous than you fear, or that you can cope with some uncertainty. Excessive reassurance-seeking may briefly quieten one worry, only for another question to arise.

Some safety behaviours are less obvious, such as planning every sentence in advance or only going out with someone who makes you feel safe. The aim is not to take away all your sources of support. Instead, you explore what they do for you, their costs and what might gradually become more flexible.

Gradual exposure

Exposure involves gradually approaching some of the situations you avoid, where they do not pose a real danger and where this work is appropriate. The steps are planned together, with your agreement. It is neither a test of courage nor a confrontation imposed on you.

If speaking up is difficult, one step might be to ask a brief question in a chosen setting before considering a longer contribution. The aim is to observe what actually happens and learn to act while experiencing some anxiety, rather than waiting for it to disappear completely.

The pace and exercises are adapted to the individual. Exposure is not automatically proposed for every concern and does not mean putting yourself in a dangerous situation.

The physical sensations of anxiety

A racing heart, muscle tension, a feeling of tightness, dizziness or restlessness can accompany anxiety. These sensations can themselves become worrying and feed the cycle: “If my heart is beating this fast, something must be wrong.”

The work may involve understanding these sensations and learning to experience them without constantly monitoring them. Depending on the situation, this can mean becoming more able to tolerate discomfort and distinguishing a sensation from the worrying interpretation attached to it.

These symptoms are not specific to anxiety, however. New, unusual or concerning symptoms need medical assessment and should not automatically be attributed to a psychological cause.

What tools can be used in CBT?

Tools are chosen according to your circumstances and the goals agreed together. There is no single set of exercises applied to everyone. Possibilities include:

• Observing triggering situations and what happens before, during and afterwards.
• Identifying automatic thoughts and the associated emotions and sensations.
• Cognitive restructuring to examine interpretations and consider alternative explanations.
• Behavioural exercises to observe what happens when a response changes.
• Gradual exposure, where it is relevant to the difficulty.
• Exploring habits of avoidance, checking or seeking reassurance.
• Between-session exercises to extend observation into daily life.

Your feedback matters. If an exercise is too difficult, unclear or poorly suited to you, it can be reconsidered. It is not a test you have to pass to be a “good client”.

How long does CBT for anxiety take?

There is no duration that is right for everyone. The intensity of the difficulties, how long they have been present, their impact on daily life and your goals all influence the pace of the work.

The first sessions help clarify what you are seeking. Regular reviews then consider what is changing, what remains difficult and what needs adjusting. It would be premature to specify a fixed number of sessions without understanding your situation.

Is CBT suitable for everyone?

CBT can be useful for various anxiety-related difficulties, but it is not automatically the only way to work. Its suitability depends on your concerns, circumstances, preferences and needs.

A broader understanding of your history, relationships and recurring patterns may also have a place. Practical tools do not prevent us from considering what your experiences mean to you. You can read about my background and way of working and discuss an approach that might suit you. Referral to another professional can be considered when your situation calls for it.

Can CBT take place online?

Consultations are currently offered by video, in French or English. Where appropriate, remote work can include discussion, observation of situations and preparation for tailored exercises.

A quiet, private space and a reliable internet connection are needed. If you are seeking therapy for anxiety in Strasbourg, you can read more about CBT at the practice and discuss your circumstances at a first appointment.
