Looking younger than you are

Does anyone else have this problem? I'm 22 but look like i'm 15 so I get carded for EVERYTHING. This weekend alone I was IDed for cigarettes and while buying tickets to that new Paranormal Activity movie. It just sucks because people always treat me like I don't have anything worth saying and I feel like I can never have a boyfriend because anyone my age will want someone who doesn't look like they just started highschool.Has anyone had to deal with this?
