Going away for 7 days 3 hours from my house - nervous?

I am attending a 8 day Flight Academy starting June 4th - 12th. I will be alone with people I don't know from around Illinois. I am very nervous as this is going to be the longest time I've been away from my parents ever. Suggestions? I am very nervous. It is through the Air Force (I will be getting my Glider Pilot's license) but not really "military strict." Common courtesies and respect, but it won't be military strict. We will fly, take showers together (I don't like that), see movies, play games, and BASICALLY FLY THE WHOLE ENCAMPMENT + tests for licenses. I really would like suggestions on how to overcome the stress/nervousness, thanks.
