If you look at it from her perspective it might be a bit creepy since she doesn't really know you =/
The best course of action is probably to just talk to her at school a bit, and then some time later ask her out on a date. You can take her to dinner or lunch or something, or go see a movie or a play, or just invite her over to hang out; I'm not really sure what you (and she) are into. That will make it clear that you're interested in her, but it won't put pressure on her to make a decision quickly, and honestly your chances are much better if she gets to know you first.
I'd follow TAY's advice Shelcario, as he has the right point, so what if you can't socialize well, at least try it nigga!
