Last spring my Dad had a major stroke at his brainstem that landed him in the hospital. He was in a coma for 60 days and deteriorated with no movement or awareness- he was breathing on own but barely. This happened right after schiavo was in the news- but we never spoke about it. I found out from Mom that Dad had given me medical Power of attorney- His living will said no life support whatsoever. The experts said his condition was worse than Schiavo. I then had them remove the feeding tubes to spare mother more pain.
For five days he withered away with no change- on sixth day he moved his head, looked up his eyes slowly moved and he stared at me. I had hospital give him a sedative and he went back to sleep. He died that night.
I see him staring at me every night in my dreams. It does not wake me up anymore-but the dream comes every night.
I think I would have has closure had I spoken to him in person of his intentions rather than find out whilst he was comatose.
My Mom is doing fine, although she also really misses Dad.
I am hoping thinking of Mom being OK will bring me closure.
But it'll probably make you feel better if you realize that your father was dead after his stroke. You're lucky (and so is he) that you don't have a family that forced you to keep him alive, so that you would have to watch him deteriorate slowly.
