My mother had an extreme case and tried to kill herself early on. She was hospitalized in a mental ward twice and they said because she was hospitalized twice in such a short period, she would be kept the third time. She's chased away most people except her immediate family whom she has a rocky relationship with. On its onset, she walked around with a tin foil hat and thought the neighbors were spying on her. I don't know if she had hallucinations because she doesn't talk about it. She only mentions that she knows what people are trying to do to her occasionally but she trys to obfuscate her condition and she doesn't take meds. She's become ultra religious to help cope but it's given her a messiah complex. It's actually destroyed my life and ruined my relationships with people in the neighborhood that i grew up with and girlfriends that i introduced to her. It's very hard to tell if she hates the person because of a legit reason or because she thinks they are a literal demon. It's also made me paranoid that it will happen to me.
