With time you will figure yourself out. You still have a lot of time to develop. Your friends are just giving you a hard time, because you may be slightly different. Teenagers do that. It is a way of discovering your identitiy. To start putting label and putting people in categories. It will happen a lot over the next few years, but then it won't matter. You will discover you are a person like none other. You have your own likes, dislikes and style. That is your identity and it is yours to figure out. It won't come from someone else, no matter how hard they try to label you or critize you. Learn to be yourself and what you like and don't.
