she and i both have BPD. however, she uses hers as an excuse, if she hurts someone she doesn’t apologize and says it’s just because of her BPD. i try my best to not allow my BPD to control me, and i hate seeing the things she does to people. she lies and manipulates people, she’s gotten her friend to join her in ganging up and harassing me. 

i understand it’s hard for her as she’s unmedicated and untreated, but she constantly preaches about how much of a role model she is, how amazing she is for doing everything without medication. in reality, she’s an incredibly toxic person who lies and manipulates people, treats them badly, blows up on them, and plays the victim when they decide to leave because they’re done with everything she puts them through.

she wants to be friends with me again, but i don’t trust her due to how horribly she’s treated me. how do i go about dealing with her?
