I feel like a monster for feeling this way but I'm really struggling to sympathise with my housemate with self-diagnosed depression, anxiety and ptsd. I didn't start out being this callous and frustrated with her, but I am at a point where I feel like I'm walking on egg shells.
I started losing patience about six months back when I accidentally startled her by closing a cupboard too loudly in the kitchen, she slammed me into a wall and started choking me and I ended up having a miscarriage a day or two later. I apologised to her for scaring her, and instead of apologising in return she said she acted that way because I triggered her anxiety.
I didn't think much of it at the time, I was preoccupied with other things tbh, but I've noticed she uses her mental illnesses to manipulate people into doing what she wants. She does no housework and every time I ask about the rota she says it'll trigger her depression, she listens to loud music all night without headphones because they trigger her ptsd, I've got to the point of hiding from her because she'll get physical or start screaming if I put a foot wrong. She currently lives rent free as she refuses to pay and says she'll harm herself if I ask her to leave, even though it is my house and she has no contract.
I've spoken to our friendship group about this and they keep saying I've got to be more understanding of mental illness, but I also struggle with depression and I don't think I've ever behaved like her. I even called her parents, but they keep saying how happy she is living with me and can't be moved or it'll trigger her depression further.
Does anyone have any advice on what I should do? I feel scared in my own home.
