It is you who doesn't see the obvious: Terri didn't feel anything as she approached her final release.
I hope that you are right, for her sake.
My father suffered quite a bit leading up to his death from leukemia, but in his last day he had some sort of stroke and he couldn't speak. He was aware of us all though. He passed on that night pretty peacefully.
If I said something that was wrong or callous, I didn't mean to. I hope you will accept this as an apology as well as the other poster.
