I've been with this girl for a while and she's been upset for a while and we broke up and she started being with this guy I really hate and she knows that. I asked her to take me back, we have this promise paper that's really sentimental... It's like almost the existence of our relationship and we broke up a few times but we could never so something to that paper... I gave it a shot and gave it to her today and ask her not to waste the paper... She tore it right in front of me and didn't care at all and now she's with this guy and they are planning to have sex... She's in my school and I can't see her with him.. Their always around me.. I can't do this anymore, I can't stop thinking of her, I need to die to stop this.. I can't do this, please help I need some professional help or I should just let it be and put a bullet in my head.
