The short-term relief that keeps anxiety going
Checking, avoiding, preparing, reassurance. Each one makes you feel better right now. Each one teaches your alarm that the danger was real. This is the loop CBT interrupts.

The things you do to manage anxiety are, almost always, the things that keep it going. You are not doing them wrong. They work, they make you feel better, and the feeling better is the problem.
The immediate reward
When you avoid the situation you were dreading, the anxiety drops immediately. That drop is a reward, and rewards train behaviour. Your brain notes: avoiding worked, do that again. The same is true of checking the symptom, rehearsing the conversation, asking someone whether it will be all right, carrying the water bottle, sitting near the exit. Each brings relief, and each is filed as a strategy that worked.
The trouble is what else gets filed. Every time relief follows avoidance, the alarm learns that the situation was dangerous enough to need avoiding. Every time relief follows checking, it learns the sensation was worth checking for. The relief confirms the threat. You feel better now and more anxious next time, and the loop tightens by a notch.
Why you never find out
There is a second cost, and it is the one that matters most for treatment. Because you always use the strategy, you never find out what would have happened without it. Would the presentation have gone fine without three nights of rehearsal? Would the flutter have passed without checking your pulse? Would the party have been bearable without the drink first?
You do not know, because you have never let it happen. The prediction that something terrible would occur has never been tested, and untested predictions stay in place. The strategy has protected you from the disaster and, at the same time, from the evidence that the disaster was never coming.
The safety behaviours you do not see
Some strategies are obvious: avoiding the motorway, not going to the party. Others are woven into ordinary life so thoroughly that they do not look like strategies at all. Over-preparing. Keeping questions ready so you never have to talk about yourself. Sitting where you can leave. Holding something. Speaking fast to get it over with. Monitoring your body. Having an exit planned. When I map these with someone, the list is nearly always longer than they expected, and each item is a piece of evidence that has never been gathered.
Interrupting the loop
This is what CBT for anxiety does. We map exactly what keeps your loop turning: the predictions, the strategies, the relief. Then we test the predictions in real life, at a pace you control. Go into the situation without the preparation, and see what happens. Let the sensation be there without checking, and see what happens. Drop one safety behaviour at a time, and gather the evidence.
What happens, almost always, is that the anxiety rises, because the strategy was holding it down, and then, given nothing to confirm it, it falls on its own. The feared thing does not occur. And the alarm files a different lesson: that situation was not dangerous after all. Repeated, that lesson recalibrates the system, and the loop loosens. Most people are surprised how quickly it happens once they can see the loop clearly.
The discomfort is the point
This is uncomfortable, and I would rather say so. Dropping a strategy means feeling the anxiety it was suppressing, at least for a while. The discomfort is the treatment, because it is the moment when the prediction gets tested. Every experiment is agreed in advance and starts well within what you can manage, so nothing is sprung on you. The aim is information, not endurance.
Where relief belongs
Relief has to come from the right place. Relief that comes from finding out the danger was not real recalibrates the alarm. Relief that comes from avoiding the danger confirms it. The whole of the work is moving from the second kind to the first.
If you can see the loop in your own week, there is more on how I treat anxiety, and on the specific shapes it takes: panic, social anxiety, health anxiety and generalised worry.
