I never lived in the dorms personally except for when I studied abroad for a summer and we lived in the university's hotel. I thought I would hate having a roommate, but you know what? I really liked it, and became good friends with my roommate as well as other people in the program. We all became really close because we lived together and were so far away from home.
I think it would be hard at first, but eventually you would come to really like it and could make some good friends that will help you adjust to college life. I know choosing a college is a tough decision, but hopefully you will get to visit some of them and find one you really like. Good luck!
