High school-age is rough. You're expected to fit in to one or another of the crowds/cliches/stereotypes and when you don't , you're pretty much an outcast. The good news is that it will eventually be over.
Best advice I can give is what others have said...be your own biggest fan, forget 'belonging', don't worry about identifying with anyone and celebrate your individuality and unique style.
Be avant-garde, start your own group, be the innovator, the leader, and the trend-setter. The more confidence you have in yourself and the more secure you are in your self-knowledge, the more people will gravitate towards you and want to identify with YOU.
It's ok to be alone, out in front of the pack, instead of in the middle...just one of the crowd.
