CRANKY IS GOOD ............ It means they are well enough to be upset w/ the situation. Just don't take it personally ! So glad to hear from you, I knew ,from experience, when family doesn't talk... things are bad. Give him a hug from all of us... and yourself as well.
Now it's important for you to take care of yourself. In between your visits to him, get a bite to eat and lay down. Don't forget to get fresh air, hospital air gets after a while.
Do what ever YOU need to do... I cleaned drawers... why?because that was the only thing I could control everything else was out of my hands. My 2 y/o son had brain surgery, to make room for an inoperable tumor. 18 years later he is still hanging in there, but it was the hardest thing I ever went...
