Confused, I need advice, I may be going insane...?

Here's the thing, being a teenager is difficult and confusing because you don't know who you are. However, if you don't want to do something, the answer is plain and simple: DON'T DO IT. The fact is, one day you'll figure out who you are and what you want to be. The fact that your style fluctuates means nothing. Experimenting with different looks allows you to get a better grasp of what you would prefer. You're not going insane, you're just finding yourself.
