OP, you're worse off than I ever was. I wasn't able to walk around public unless I had one of my friends with me, and that didn't happen very often because I've never really had very many friends. But, luckily, I was eventually able to do what I wanted outside of my room without getting extremely nervous. Now I go out every weekend and take it easy. Even casual dating!

(though I still need a friend with me if I'm just walking around town, I get so concerned with not having a breakdown somebody's gotta watch for cars ( ´･ω･)
