Tired of fighting

I am 15 years old, leaving my 8th grade year. I consider myself a "modern hippy". I have an amazing girlfriend and a few true good friends. Most of my friends are considered "popular" on the social scale, along with me. But the normal "expected" clothing and such from people is not what I wear or do and I find myself getting tired of justifying myself to everyone. And when I really get sick of it I think "screw it, I'll just get different friends" but then all I can think of is that they would be "nerdy". And I think its an asshole thing to think but I like being popular and I guess I'll have to keep fighting for who I am. Does anyone else have a similar situation?
