Maybe try growing relationships with the people you talk to you in your classes. You could start small like asking if they want to have lunch together, or get together to work on an assignment, etc. If your college has a gym with exercise classes, this can be a good way to meet some new people, find a class you like and go regularly. When you pass by some of these people you chat with, smile. Are you in a single room? On weekends, maybe prop your door open, if people are gathering in your hall.
