That's just how it goes and to me you being aware of yourself like you are at this age is a very good sign. This means you'll always be aware of yourself and your behaviors. You should be proud. As far as feeling guilty for things you did as a kid, that's no biggie. I recommend just letting that go. As a sociology major, I can tell you that preteens and teens almost always conform in some way or another, it's apart of socializing, which is human nature. Don't feel guilty for that, everyone has done this.
