Ok, guys, i need help, depression and prozac Options

Ok, guys, I need some help. I made a post about przac before, and my girlfreidn has been taking it for a week and half. She got into a fight with her parents today and feels like she did 2 years ago before she tried to kill herself. She can't control herself, and she feels like she wants to again. HER PARENTS STILL WONT TAKE HER OFF IT. I seriously think that if I don't find somehow to get her off of it, I might seriously hurt her parents, and I don't want to spend time in jail. Please help me... I love her so much, and I feel like there's nothing i can do... thanks in advance, Shonenman

Thanks, guys... I'm fine, we're getting help tomorrow. I'm fine, I was really upset and wasn't thinking clearly at all. We're fine now, we're going to ask someone outside of the situation. I kind of went psychotic on you guys. Sorry about that, and thanks for the help everyone's given me. I greatly appreciate it, and I owe you, so feel free to ask for a favor. Thanks again,
Shonenman
