I feel for you, but this is a decision of your conscience, and how you will honor your mother.
We all die. Maybe it is her time. I've dealt enough with death to know that we honor people when we let them choose their time to go. Sometimes, people need a bit of help to get past their own fears, Whether for their own death, or for the death of a loved one.
My father degraded with Alzheimer's for several years, eventually getting quite difficult to manage, as he was unable to feed himself, would schit everywhere, and then got violent. My step mother, who had taken care of him, finally was at the end of her rope. My two brothers and I convinced her to take a break, and put him in a home for a couple months. We all knew what the outcome would be. We all knew it was his time to go, but he couldn't leave his wife for some reason. We each did some serious soul-searching before recommending that course. He was in the home for four weeks when he passed. We did the thing that felt right to us. Much of the time, life (and death) don't look pretty. That doesn't mean we haven't done the right thing. Life is just messy.
I think the problem may not be dying, but starving her.
Dayom. Prayers sent.
