A lot of kids are in the same situation as you. My advice is to force yourself to talk to people. Especially during your orientation today. Everyone is nervous to some degree but being friendly and open to conversation is the first step to making new friends. Also, Leave your dorm room door open while you are in it for a few days to show people you are open to speaking to whomever stops by. Good luck. You got to where you are, now conquer this next step!
