Bobbi what an awful situation you are now in. You will just have to continue to try to cope a bit more by herself. That is going to be very difficult as far as I can see. My sil was pretty much the same and just refused to do anything for herself relying totally on her brother and me. Made very hard work of it until we managed to persuade her to go into a home. Then she was difficult as she refused to get out of bed or feed herself most of the time and certainly would not join in with any of the activities arranged by staff or volunteers. Made all the more difficult as she still had all her faculties (hearing, eyesight, speech, ability to walk, etc.). Nothing wrong with her except being bloody-minded saying other people were there to look after her.
Maybe your friend is of the same mind set. So i do feel for you but can see it getting to be a great burden for you. You need the help of others to deal with this. I know you are a very kind person but eventually the situation will take over your life so please be careful.
Hope you don't mind me saying this. Just thinking of you.
