Why does it have to be like this?

It doesn't have to be like this, if you want it to change. Been there, done that, even got the t-shirt. Your time will come, kiddo. Girls are weird, mysterious, and impossible to figure out, but you are going to have to market yourself to them if you want a boy/girl relationship. If you are skinny, try some weight training and diet changes to add muscle m. You may want to change your hair style and/or wardrobe. I'm not saying to look like Robert Pattinson or Taylor Lautner, but it wouldn't hurt. See what the competition is wearing - if all the guys with babes wear Hollister or other branded clothing, then start wearing what they do. If you don't participate in any school activities, start now and widen your circle of acquaintances. And remember, do not aim for the top girls on campus, they are prabably taken by some senior already. There are cute, quiet girls who are in the same situation you are, nerdy and nervous, unsure of their looks and hoping for a boyfriend, and they could rock your world if you have the guts to approach them.
