My mother has some serious issues and is definately suddering from a psych disorder. She makes constant threats, screams and cusses at everyone/everything, believes the world is out to get her, leaves garbage lying around and blames it on everyone else, steals constantly, thinks she's entitled to everything, she's addicted to pain killers, addicted to the internet, and she's a hoarder. She also has a disturbing, bordeline sexual obsession with my sister's body. She spends every penny of her SSI ($800) on cigarettes and Facebook games. She can't speak coherently and gets angry when people don't understand her. We believe she may have a form of schizophrenia, but she refuses to see a doctor because she believes it's all just a plot to get "her" money, which is actually my sister's money. My sister has been taking care of her but is tired of having her money stolen and credit destroyed (six years ago my mother got a bunch of credit cards in my sister's name and maxed them out in less than a week, more than $10k).
Is there anyway to force an adult into treatment, or at least an evaluation?
