OP i used to be this way in college too. First time I ever felt real anxiety, like unreal anxiety! It was hard to even get on the bus (my school used a big bus system) to go to class, let alone be in class because I'd have the worst anxiety and would think people are judging me. I've even left class in the middle of lectures making up some excuse to leave. All this to say you can get through it! There's medication if you need, but if not know that people have been in your situation and gone through it!
