I used to have this problem way back in middle school... and let me tell you, all of the people who bothered me about it either dropped out of high school/college, or went to the only college that would accept them (ranked like 1000) and are now unemployed.
The 'popular' kids usually don't do well in life. It happened in my parent's lifetime, and it's currently happening in mine. One of my best friends, who played pokemon with me back in middle school, is graduating from the same university i am and is going to work for Microsoft when she graduates. MICROSOFT!
I know at that age it's hard to do, but you really have to ignore what other people say. The reason they make fun of you is because they're insecure. They want you to 'join in' to whatever they're doing so they feel less insecure. Don't fall into that trap. Do things because you like them, not because of what other people like. We only have one lifetime!
