Try joining a club or a sports team. I have the same issue- I just don't seem to fit in with people. I focus mostly on my studies while I'm on campus and then get out as soon as I can. However, last year I joined CDG (cognitive diversity group). I thought it was going to be like group therapy but it's not. It's a club for people with psychological disorders or learning disabilities and anyone else who is interested in learning/supporting/helping those with such disabilities. It's a group of people and we all have a major thing in common- we're different. My point being- finding people who have something in common can really help get things started. I suggest trying to find a club or a team that you could join.
