I struggle with a very similar thing, but at school. I am quite different from you, so our situations are kind of flip flopped. In my high school, all the girls seems to only about sports, dating and relationships, tanning, having babies, and shopping. And for the guys - sports, sex, drugs/alcohol, fighting, and money. Stereotypical, but true. Then there's the awkward, odd-ball me. The environmentalist vegetarian who's really into creativity, art, and music and the only sport she can even relatively play is tennis, which unfortunately is considered a "hobby" rather than "sport" where I'm from.

Basically, the only advice I know of, and that I can give you is don't change. Don't try to change to meet their needs, and don't go bitter because you don't fit in. Being different is good. It's what makes you YOU, and unique from everyone else but in a special way. If you try to keep being friendly and positive, people will eventually recognize you for that rather than if you let it get too you too much and you grow bitter and stale to those around you.

So keep your chin up, and be yourself. If they can't accept you for who you are, they aren't worth being friends with any way.
