Elder care lawyer will be able to answer questions and advise on estate matters. Usually get the first hour free, I got all I needed in that hour. Doc can get her on Hospice and they will send out a nurse a couple times a week to check her, will also send out a bather couple times a week, provide adult diapers and bed pads, provide hospital bed and other equipment as needed. You have to hire sitters if you go that route. Don't hire just one, two is good three is better. Hopefully you have POA and are on her accounts, if you are not on her SS account as a contact they will not talk with you even with POA. My mother moved in with my sister. We had a sitter come in seven days a week 10 hours a day. I would go over most every night and get her in the bed and settled. It was rough and my wife helped a lot, you can't do it alone. It was a tough 3 years but I would do it again.
Prayers for you and Mom.
