Since someone necro'd the topic by a few days [Insert death glare]:
You have a case of one-itis, your obsessed with one girl and you cant seem to get it into your mind that It's Over". Judging by the situation your roughly 16, you have ALOT more to live to, ALOT more women to meet and clearly she's being completely rude to you and using you as her emotional tissue and discarding you once the booger and tears are drained from her to you (not literally).
BASICALLY: She's trash, move on, Plenty of women to see and meet, your still young, stay in school, don't resort to drugs and no its not dorky to resort to advice on a Gaming forum since some of us could be either doctors or Youth Advisers (Points to Self)
