Most people first meet cognitive behavioural therapy as a single sentence. CBT, the sentence goes, is about challenging negative thoughts. True, in the way that a driving lesson is about pressing pedals. I am a CBT therapist, so I have an obvious bias here. I also know it does not suit everybody, and it is not the only route out of anxiety. What I can do is tell you what the work actually looks like from the inside, week by week, so that if you are weighing it up you know what you would be signing up for.

Before the first session: what you want to be different ?

Therapy starts with a goal, and “I want to stop feeling anxious” is not a workable one. Anxiety is not the enemy. It is your body doing something it evolved to do, and nobody switches it off for good. The useful question is smaller and more concrete. What is the anxiety stopping you doing? Where does it show up in a normal week? Then we make the target a behaviour rather than a feeling. Getting back on the train. Going to the meal without rehearsing an exit. Speaking in the meeting without scripting it twice in the shower first. Feelings are the last thing to move. Behaviour moves first.

Session one: the map, not the lecture

A first session is not a taught lecture on the cognitive model. I ask for one recent moment when the anxiety turned up, and I ask for it in detail. Where were you? Who else was there? What went through your mind, in the words it actually used? What did you do? What did your body do? Then we draw that single episode out on paper together. It still surprises me how much of the whole difficulty is already sitting inside one moment. Nothing is general and nothing is theoretical, which matters, because vague questions get vague answers, and vague answers change nothing.

Sessions two to four: the part people don’t expect

Popular writing talks almost entirely about thoughts, because thoughts are the easiest corner to describe. But the cognitive model has three corners, and the corner that keeps anxiety topped up is behaviour. Safety behaviours are the ones I mean. They rarely look dramatic. Arriving early so you can pick a seat near the door. Checking the route three times. Preparing a story in case anyone asks what you do. Taking one drink to take the edge off. These are sensible, understandable things to do, and they work in the short term, which is exactly the trap. Every time you get through something with the crutch, you learn nothing about what would have happened without it. The frightening prediction never gets tested, so it never has to face the evidence. Safe, and stuck.That is why the beginning of the work often looks like doing, not thinking. It is the harder place to start and it is the reason the rest of it holds together.

The middle sessions: exposure, built like a ladder

If there is one active ingredient in CBT for anxiety, it is exposure. That means approaching what you are afraid of, on purpose, in a planned and graded way. It does not mean gritting your teeth and flooding yourself until something breaks. Think of a ladder. The bottom rung should feel uncomfortable, and only mildly so. Take someone frightened of driving on motorways. They do not begin by joining the M25 motorway at rush hour. They sit in the parked car and imagine the drive. Then they ride along as a passenger. Then they drive a short stretch of dual carriageway at a quiet time of day. Then further, at a busier time. Every step has to be uncomfortable enough to count and small enough that it actually gets done, and calibrating that is where most of the clinical judgement lives, because too small means nothing is learned and too big means the person is set up to fail, which teaches them something worse than they started with. Safety behaviours come out of the plan deliberately, one or two at a time, not all at once. Ladders, not leaps. That is the bit people are surprised by.

Later sessions: the therapist does less

A good course of therapy should make itself unnecessary. The aim is not to feel better for one hour a week, it is to leave with a method you can run on your own. By the later sessions I am deliberately doing less and the client is doing more. They set their own tasks. They spot their own unhelpful predictions, in their own words, before I have noticed them. When that starts happening, the work is nearly finished, and the last session feels less like an ending than a handover. Part of that handover is a relapse plan, written down, because anxiety does come back at stressful points. Coming back is not failure. It is weather. When it doesn’t work CBT is a doing therapy. Most of the change happens between sessions, and that means it asks something of you at a point when you are already tired.

That is a real cost and it is worth knowing before you start. It is also not the right shape of help for everyone, and it is not the right time for everyone. If the main difficulty is grief that has not been given room, or a trauma that is still too raw to approach, or a situation that is genuinely unsafe rather than misread, then the work needs to be something else first. A poor fit with the therapist does the same damage. You can do everything asked of you and get nowhere if the person in the room is not the person you can talk to.

Having CBT once and finding it didn’t help is not evidence about you. It may have been the wrong moment, the wrong shape of support, or a room where you couldn’t be honest. All three are fixable.

What to ask before you see a therapist

Four questions, and the answers tell you a lot.

How much will I be expected to do between sessions, and what does that look like in a normal week?

What would you be working on with my particular problem, specifically?

How will we both know it is working, and what happens if it isn’t?

And do they have a fixed number of sessions in mind before they have actually met you, which is the one that should make you cautious, because the work takes the time it takes.

Anxiety responds to evidence gathered in your own life, not to being told to relax. That is the whole idea. It is slower than people expect and more ordinary, and it works. Guidance for generalised anxiety usually puts a course at around 12 to 15 weekly sessions of an hour, so a number in that range is a fair planning figure. It is not a promise, and no one should be making promises before they have met you.
