It's all just chemicals in your head man. Hate to sound like a douche, but the cold, hard truth is that your "feelings" were/are just oxytocin. Anyway, King is right. Just wait until college (and in the meantime you can try to bag other girls in your school, hopefully winning back lost respect and possibly making her jealous, though that shouldn't be your goal, just a potential positive side effect).
Jealousy, a positive side effect?....Bag girls like they are prizes?....Even for you that's low
I can't really say anything Mr. Illini hasn't said already, except that I've been in similar places before so if you ever need to talk feel free to PM me. Also that Deus Naturae's advice/observations/whatever strike me as hugely irresponsible and unhelpful.
Strike you? Ma'am if I do say so, you've got an impressive command of understatement.
