Sounds like your not socializing enough. Get more involved with others, but DON'T change who you are or you still won't fit in because you will be with people with different interests you truly have no passion for. It will all be a lie you can't undo. I know this sounds so cliche' but every kid feels like they don't fit in and like they are lonely. Even the popular kids or the ones who are in the "in crowd". Just be yourself and don't change who you are! Just talk to your peers a little more. Hope this helps!
