Have you had her evaluated by Hospice? If she qualified, I think this would be the most likely route to go. They are the ones you call when something happens and they will help with any arrangements that need to be made.
Hospice sounds like the best choice, starting now. They provided comfort care right up to the end, and when the end came they took care of all the details.
To those who tried to help, you have to maybe read the question again.
