It's very hard to see someone we love so much in a bad medical situation. It makes one feel so helpless. I went through a tough time when I learned my father had fallen and broken his hip. It was not good; he was never the same, and he died about 2 months later. It was such a terrible time for all of us.
My heart goes out to you. I know he knows you love him. Every display of affection is a positive and powerful thing, and so important, for you, too.
It's very nice of you to bring him pizza. I hope he enjoys it very much.
Wishing you and your family strength and please remember to take care of yourself, as well, during this difficult time....
