I had the Same problem as you. I want to do as much as I can but anxiety was bringing me down. Then I stopped and took little steps like, going to pay for something in a shop without having someone with me, and that's when I realized that most people are more interested in their own Anxiety's and fears to notice what I'm doing and the fear is all I'm my head. There are still days when I feel like an animal in a zoo, being watched by every one but, I can't let that stop me from doing as much as I can. The more confidence you have the more drive you will have to do all the things you want to. I hope this helps and sorry for the bad grammar.
