I want to go to prom but...

I really want to go to prom. I've always thought it would be really fun.. But I'm single. So I don't have anyone to go with. I know you would probably say go with your friends but most of my friends aren't in my grade and the ones that are in my grade already have boyfriends so they would be going with them.. But I really want to go but I don't think I should. Any advice? Please?
