I'm basically a loner too, so I don't think there's anything wrong with it. Sometimes I like to be around people (I'm not a complete hermit!) but I need plenty of time by myself, and I enjoy my own company. As long as you're happy with your life, don't worry about it. For many of us college is the first time we are out on our own, and it's party party party!! It can be crazy. If you feel "not normal" maybe it's just social pressure, the need to conform & be like everyone else?
