The first few weeks are the hardest. When I started I had a room mate and she and I were NOT compatible (she was all about parties and boyfriends and sororities and she looked down on me because I didn't have designer purses and stuff.

After a few months we did some room swapping and my new room mate was much more friendly and like me and wasn't there to impress anybody she just wanted an education.

I am a quiet person myself but I started reading/studying in the commons room on the floor and that gave me the opportunity to talk to the people I didn't know. Some them I ended up liking as friends, some not.

I know it is hard and you are scared and you don't know if you can handle it but this is a great opportunity for you to grow as a person in many ways. You don't have to be perfect, just give it a try.
