Hello, Saralydear. Welcome to ehealth forum.
It's been a while since I was away at college so I'm not sure how much help I can offer. One thing I know, living on campus makes college life more affordable in general. So, if you have the option, definitely consider dorm living. Also, on campus you have easier access to the school's gym, weight rooms, running track- all free. Unless things have changed drastically, dining in the cafeteria offers a wide variety of food and usually includes a salad bar, which is much healthier than ordering a pizza, for example. (Gotta watch that freshman 15!)
It sounds as though you are off to a great start to a new lifestyle. Best of luck and once again, welcome to ehealth forum.
