What’s wrong with her?

Hey guys so my mom is very bitter and people say she’s pretty evil. She has really bad mood swings , makes up lies all the time about people, constantly Complains about how much she hates her husband and how her children are letting her down. She’s religious well claims to be anyway she talks about how much her children are fallen into the evil path and the devil is after us(crazy right) . I’m so tired and sick of her I thought about putting a restraining order on her only because she once had hit me because she thought I was lying when I wasn’t. I thought she was bipolar but I think it’s far more than that . She also claims that she sees spirits. She is also very controlling even though her children which are my brother and sister both of them are 25 , she seems to care about their life a lot . I thought she was a narcissist but i think it’s much more than that. The stuff she says no mother should ever say to her child. Can someone tell me what do you think is wrong her she’s been like this for years ?
