Am I doing something wrong? ... =(

I think that changes of environment are always good to help start over. Especially if you've been in an environment that isn't good for you for many years. It sounds to me like you didn't have a fun time in highschool, but i'm making some assumptions here, so you can set me straight if you want.

You're going to a music college next year? that's a good step. You'll be surrounded by people you've never met before, who have nothing to prejudge you on, and, i'm assuming you'll have much more in common with these people, namely a love for music. Just be as friendly as possible, and always try to remain true to yourself, and you'll make long lasting relationships as you go through college.

How ya doing, buddy?
