Look around at all the "fat and ugly" girls holding hands with some guy. What others said about loving yourself is good advice.

I heard once that what attracts most guys to a girl is when the girl takes an interest in the guy. I don't have any experience in these things actually, but my two cents.

EDIT: I am a guy though, and I can say that I would have always been willing to trade my fantasies for a normal girl that cared about me. Now I'm 50 years old, so it won't be something I experience. You're young, so I bet you will find somebody. Most people do eventually.
