Hi so I live in a household (renting) where this girl has BPD and the mom does not but the girl told me that when things are peaceful that she has this itch almost that makes her want to start drama and mess everything up. She would make a mess and blame it on me, tell people made up rumors about me, and get insecure about me being around her boyfriend (we all live under the same roof) even though I have him blocked on everything and I don't even talk to him and she still causes issues with me over that including telling me she'd kill me or take my life. The mom can't deal with it anymore because the girl refuses to take her meds which I understand sort of because I take depression medication and it numbs me out but I can't take living here anymore it's driving me insane how do I live with this? I bring my best friend over and she tells her mom that my best friend stole her shampoo and conditioner when she didn't even shower at the house. Idk it's a lot for me, I just have extreme anxiety and she keeps intentionally making my life worse by stealing my things, causing issues, and spreading lies. Blames it on the BPD but doesn't take her meds and makes excuses and I don't like confrontation but when I did and I had video and photo evidence of something she did she denied it straight to my face so there's no accountability here at all. I asked my aunt for advice and she just said I need to understand where she's coming from so I came here, I don't understand no matter how much I research into this. Please, how do I keep peace?
