CBT is great for anxiety, but you really do need a good therapist, so if you don't feel you vibe with one, please try another one. Alas, the NHS sees it as a cheap option - but 6 sessions with a great therapist is very different to 6 with someone who is shit - and that doesn't always come down to the level of qualification.
You can also tell a good CBT therapist by whether they use experiments to test the validity of your beliefs. If they only tell you to deny your thoughts without disproving them - new therapist.
But as a real great intro, and also as a mantra I found really helped me, the book 'Feel the Fear and do it Anyway' by Susan Jeffers was great.
It reminded me that it's ok to be afraid, and actually, eveyone does. All that differs is how you respond to the fear.
The more you do something, the less you fear it. For example, if you or I were asked to parachute jump from a plane, we'd probably be really scared. But if you are a member of the Parachute Regiment, jumping out of planes regularly, it's of no matter. Ditto jumping off the highest dive board and Olympic divers. Etc etc.
So the thing you fear most? Do more of that.
Also, looking at breathing exercises for hypervetilation can make you less likely to panic. Be sure they are exercises you do several times a day, not ones to only do when you are panicked or feeling anxious. (DM me if you can't find any and I'll send you mine - I've not been a physio since 2021 tho).
