My "friend" is ruining my life. How much more drama can I deal with? How much more of her mental illness can I put up with while she's ruining people's lives, and ruining my friendships?

I cant win. I'm scared.

This isn't making my depression any better. Far worse. I know I'm giving her control over my life in some way... but I'm trying to be positive, establish boundaries and all that...

But she takes it out on me. It's always my fault.
