Idk which category to put this in, I hope this is okay. But my sister drives me insane. A little background:

Growing up, we often shared a room. So that got old fast. And when I was 5 or 6 she would hit me. She's always been stubborn and has anger problems. I used to be like her, but I changed because I realized it was wrong to act like her. Shes ignorant as hell, is a compulsive liar, and is emotionally abusive/manipulative.

Now to more recent things:

Her and her husband recently got into a major argument to the extent where my sister threatened to hit her husband. I know she needs help, but she wont admit what she does is wrong. She has manipulated me into putting her needs above my own. And when I said I needed to do some dishes or cleaning, she would act all disappointed and try to guilt me into changing my mind. My grandma is also a compulsive liar, but her stories are more out there and less believable. So I guess my sister took notes on what not to do. But I can tell when she's lying. And she is emotionally abusive because whenever her and her husband get into an argument she always pulls the "You dont care!" card and blah blah blah.

Btw she lives upstairs in a house and I live in the basement suite.

But idk what to do. Sometimes I hate her. I cant move out cuz I dont have the money to. So idk...what would you do?
