At University there will be far more people for you to mix with, so you are bound to find a group of friends with whom you can bond and settle in with. People will also be far more tolerant and more willing to be out going.
I really do wish you all the best - I'm currently away from school due to certain *legal problems* so I'm unable to meet and see all my friends. Only two people actually know what's going on, so I can sympathise about how you feel. Things will get better they always do.
