<human>: I feel like shit. Everything she told me she was and she even showed me she was, she turned out not to be. She went to dance like a slut with half the guys from school and was totally drunk. She told me she missed me but that she had already been seeing other guys. She said I was always perfect and that she really wished I would do everything to get her back (she said this while being drunk, so yeah, call truth?) but the next minute she was dancing like she wanted to get raped.

I can't get my mind off her and i've been on NC for so long now and I was finally doing great, I am feeling even worse than I was after the breakup.  I feel myself checking upon her ALL THE TIME and now all the sudden she blocked me on everything (I didn't even send a message or something).

How the hell do I get over this, all again? I am sorry for my use of language, I just feel so confused and I don't even feel like I'm in control of my feelings. I have the most important exams of my life in a month and i just CAN'T GET MY MIND OFF HER. 

My god, this post is too desperate, I just don't know what to do

Could you distill the essence of the text into 1-3 sentences?
