My dad is a fully functional 74 year old man. But in the past year, he has become so depressed, he is not taking care of himself or anything else. And I believe his cancer is back. My mom, the love of his life, passed away from cancer last year. I had a younger sister who was a bipolar drug addict. She had a son whom my parents have full custody of. 2 months ago, my sister died of an overdose. I'm doing everything in my power to try to take care of them, but with the condition my father is in, his health is getting worse and he won't take care of anything in the house. My nephew is also not getting the attention he needs. Its such a delicate situation, I feel that the best thing I could do is have them move in with me. I'm married with no kids and my husband feels like this could benefit all of us. I've talked with my dad and he just refuses to listen. I'm not sure what to do, because the situation keeps getting worse.
