What issue do you think my mother has?!

Basically ever since we were little she verbally/emotionally abused us. She would scream every single day, curse us, say how we belong in our father's grave, he died when we were young, and so on and so forth to the point that people hated her in the neighborhood, and she hated them as well. She would have little mocking nicknames for each person in the neighborhood. She tries to sabotage all your relationships/friendships, will yell at your friends or call their parents up. She doesn't steal money from other people, but she's basically sued every single company she's worked for. When she's enraged, she'll slam things, yell, wake you up at all hours of the night, screaming, preventing you from sleeping. She'll slam doors over and over again, so you can't fall asleep. She'll try to prevent you from using the car, taking showers, cooking your own food, cleaning your own clothes, and if you do some of these things, then she'll make your life a living hell basically, she'll scream some more and so on and so forth. She hates our father even though he died of cancer more than 20 years ago. He was a really calm, nice, friendly man, by all accounts of the people who knew him, but she just has a vehement rage toward him. She'll also mess with your head in subtle ways, say how you have a deformed body, how you're ugly, not as pretty as other people. She defends my brother who's basically a criminal in his own right, but if you're the quiet, passive one, she'll hate you to no end. So yea...what do you think is wrong with her? What type of disorder do you think she might have? It's hard for me to tell because I'm in the eye of the storm.
