I know what you mean! I'm the same way. I'm in college now (a junior almost senior) and I find myself doing the same. However, what I like to do is take walks around the campus, rollerblade(my fav thing). Anyway, find a park or if ya can get to your campus, walk around it and make yourself more familar with it. AS for food, omg, I know its hard, esspecially around finals*makes a face* and such makes food more tempting. But I found that if you exercise, I do not become as hunger.
