Wow, it is pouring on you. I am glad your sister is making strides Steve. Things sound better. I am sorry to here about your Dad, I can't believe what a long life he had, but except his currant health problem. Some times as they age the heart gets weaker and congestive heart problems can cause fluid build up. Always remember he has had a longer life then I think any of us expect to have, each one a blessing, but your Dad may have been depressed in the nursing home wanting to be left alone. Go see him, if he can talk, have him share his great memories and hold them close. My Dad was 76 I was 46 when he passed and I miss him still. But, I have so many things he told me about the last several months he was with me.

He was living with me, but I kept his home next door going for the earlier good days. The last few weeks he was preparing to leave, sad, tired, but verbalized want a fulfilling life he had.
My prayers are with you and your loved ones.
Love you,
Di
