Whats Wrong With Me?

Ever since I've been a young child I have always had problems with socializing and making friends. I have always felt awkwardness when speaking with people and now that I am older it seems to be getting worse. I will begin my second year of college and seem to be regressing socially. I moved to a new city for cles thinking that would help but I think that has much to do with my failures. When I am in cles I often have to leave early because I feel shortness of breath, chest pain and nervousness, this is the same when I am in a situation when talking with a lot of students. I also find it hard to sit down for a long time when around a lot of People, I feel antsy. The crazy thing is that I feel those same nervousness feelings from just thinking those things! Needless to say I spend much of my time at home. I feel as though I am not maturing at the rate because I avoid social situations. Does anyone know of any medications or exercises that will help. Has anyone experienced these feelings themselves and have gotten help? Please no rude comments.
