My own worst enemy...

I know that I am high strung and stress myself out at times, but that doesn't seem to help me stop doing it. I have higher expectations for myself than most of the people around me. I've always been the student that assumes they were the one who screwed up when the instructor addressed the entire class about an issue. Even though papers are written and grades are turned in, I'm still nervous. In my mind, someone is going to figure me out at any moment and say that I don't belong here.
