Amee, I know what you mean by the spirit no longer being there. When my aunt died in Dec., she was already "gone" the day before. She was nearly comatose. I could tell that only her body was hanging on. Even the day before that, she was unable to speak--just mumbled something I couldn't understand--and just looked so miserable that I cried when I left the room and prayed to God that she would not linger on and on. She was a very special person--loved life and people and was always joking around, despite not being able to walk (result of an accident at 13.) I knew she was miserable just laying there.
I pray your family's ordeal will soon be over, and so will MIL's.
Hugs,
Connie
