First of all, it would help all of us if you could tell us your height and weight. Second, at 12 most girls only like guys that they hang out with, or are their friends. Most of the time it developes from a friendship, to a crush, to a dating relationship. For right now, just get some friends. Be nice to people. You'll be surprised by how many people actually will like you for who you are. There are people out there who feel the same way you do, and will understand how you feel, so don't think you are the only soul on earth who has to deal with a social problem. Finding someone who relates to you can give you a great friendship, and if it's a girl, you might just be lucky enough to like each other for more than friends. If you go looking for love, it will avoid you, just sit back and relax and it will come knockin' on your door! Good luck.
