I hear that, i thought the same that i couldnt do anything about it and i took meds but they did ease it a bit but it wasnt ideal so i stopped and decided to try and just do what i can and extend the length of time before i get anxious, it takes a lot of skill
my anxiety was really bad about 2 years ago i remember i wasnt doing much maybe an hour in an office but i’d get super anxious,
but since doing that i have been trying to build up my tolerances and extend my anxiety range which is make longer the time before getting anxious and coping with stress better,
so now after becoming more active physically and mentally my anxiety had reduced, its like intensive cbt without the pressure at my own pace,
I believe it is psychological for me but it is buried deep down and anxiety is a byproduct of my psychological distress
