She and I have been best friends for seven years.

I have discovered that my friend is a walking marital sabotage. She spreads rumors and -lies- for the soul purpose of leading men on and tearing apart relationships. She belittles me constantly because I'm not as "classy" as she is. And she's purposefully manipulative, an uses her depression problems as an excuse. She fucks people over and then just shrugs and says "Well, I'm crazy."

I'm so sick of it. I am physically ill over this. And what pains me more is the fact that I have been her best friend for -seven- years. She thinks that I can't see right through her lies, and she thinks that her "mental" problems justify her actions. 

I have severe PTSD and I'm bipolar, but I have never, ever treated people like she does. I have never used these things as a crutch. 

I just can't do it anymore. She's in a mental hospital right now and after two days there she causes a SHIT STORM between two friends of mine because she is now trying to sabotage those two. The thing is though, those two are very dear friends of mine. It was the straw that broke the camels back. In two phone calls she almost tore those two apart and made me look like shit. Luckily, its all resolved now, but I'm at the point of wanting to fall over and cry for a while.

What do I do, reddit? How do I explain to her that unless she gets her shit together I am DONE?
