Yes, I was going to say the same thing as Mr. Silver. My MIL is in a really nice assisted living place in AZ. She had little money, which was quickly spent down, so she could qualify for state assistance (they have their own Medicare system in AZ). There was an emergency situation where both my MIL and FIL were hospitalized. In 3 days my DH and his siblings: emptied out their apartment and moved/had their stuff taken away, did a power of attorney, and had plans for their placement when they were out of the hospital. They used a social worker who specialized in elder services and a lawyer who did the same thing.
I know you want to bring your mom to your home, but, please try to think of your own life, and how this would impact you. This is a difficult situation that can quickly deteriorate. I know many people disagree with my opinion, but I think it's OK to think of yourself here.
