A bit of backstory. My aunt went through a very bad divorce with my uncle. In the course of one year she went from having a solid marriage and a 2 year old bought house to absolutely nothing. As a result of this divorce, she lost her husband (obviously) and her house. After that, she found an apartment and a job, but she still didn't seem to recover from the big hit. She spent her whole free time smoking and sleeping till very late hours and a few months later she quit the job and got in debt. So she is basically a wreck and my mother took care of her (she is her sister). However it doesn't seem to have done a good thing as she spends most of her time closed in her own room in our basement. She can spend days without getting out of the room, and I can often see her smoking and sometimes crying. This is irritating my father a lot as she basically has taken the whole basement to herself and we can't even rarely go downstairs anymore due to privacy issues. The worst part is that she is starting to hallucinate after telling my mother that she is hearing people talking about her, when the only people that are on the house are my parents and they are out working most of the day. What should we do here? I get the impression that she needs professional help but my mother still believes she can help her by keeping her in our house.
