P.S. - please do find out as I know this must be overwhelming for you. You need some help! You can also hire a private company that could provide a home care worker that would help with some of this - I know when my father was ill, and came home, my mother was in no shape to be able to provide the type of care he needed, and since my sis and I both work full time we helped find a wonderful woman who came in every day to help with my Dad....
sorry you are both going through all of this, and I hope and pray for you that things can start improving soon...
