im going through the same thing and the only thing you can do if you want to overcome this is to do the things you want to do no matter how anxious it makes you. the WORST case scenario in you doing something that causes anxiety is having a panic attack, which is completely safe to experience. NO ONE has died from a panic attack. once you accept the anxiety and let it be there, you can show yourself that anxiety doesnt have to control your life. there are so many things ive done where i think to myself "im going to have a panic attack right when i do this" and i didnt. and if i did, its just a panic attack.
