Please just let him go now.

My heart felt sympathies to you and your family.
It's not easy watching your parents health slowly deteriorate.

Both of my parents and my wife's parents health slowly faded.
My parents and my father in law with lung problems and my mother in law
with cancer.

It doesn't make it easier to handle if you are there when they pass.
I was at my moms bed side, but I wasn't for my dad he was in a hospital
in Denver. I'm glad my mom and brother were there with him.

Your dad is no longer suffering in pain any more that's a blessing.

Take care Mike
