Hi Riley,
Nothing is wrong with you. Please remember that. Not a thing is wrong with you. You are NORMAL for a 15 year old. I'm only 15 years older than you, and I can vividly remember that age. It is tough. I can imagine it is even tougher in this current society where everything is about IMAGE. Seriously, it's not that important. The celebs and media just want us to think it is, but it is NOT. That said, I can understand how much you would want to fit in with a group. This is a very natural instinct for humans, so get it out of your head that something is wrong with you. Reading your post, I think that you're the type of person who pays a lot of attention to detail. Are you artistic? Don't try to fit into a mould of what you think you should be. Create your own look. Mix the 2 if you like those styles. Then, you will be unique. I would say shift your focus onto doing something productive and creative. If I had to guess your personality based on this post, and recommend an activity for you, it would be theater. You may find a lot of enjoyment in that. You get to dress in costume, and experience different characters just for the fun of it.
