I will assure you that what he saw WAS hell and IS.
I took care of a wife for 4 years and 5 months with a brain tumor (glioblastoma)
and for 2 years and 6 months of that loaded her on a plane to take her to MD Anderson in Houston Texas..
I can tell you stories that would make any story from hell pale in comparison.
I can still remember having the TSA at Bush International (or is it intercontinental?) empty out the entire women restroom because my wife couldn't figure out how to get out of the bathroom stall.
The police emptied it out and I went in and found where she was and had to crawl underneath the stall door to get her out..
that's when I knew I could never leave her alone after that....
Then there was another 3 years of things..indescribable..
Satan himself could not have thought of the torture that I saw.
The worst part is the hell that Bill Matthews caregivers will see and deal with and do it splendidly.
Only later suffering night after night of nightmares...that will never go away..
Yeah, he saw hell, The caregivers are seeing hell and the caregivers may well suffer from that torture for years and years to come..
Good luck Bill. Good luck and bravo to the caregivers!
