Nancy,
I'm sorry you Dad is going thru this. I truly hope for the best and quick recovery. Your being there, even though you have terrible pain and limitations, I'm sure means the world to him.
As soon as you are able, please let us know how he is doing, your Mom and how YOU are doing.
My husband is in Washington State now with his Mom, agae 88. She lives alone as his Dad died 4 years ago, in his 90's. Darold's Mom has survived Cancer 3 times about 10 years apart each time. And survived having spinal meningitis a few years ago. She is a strong lady. My husband is 72 next month.
Thinking of you dailey. your friend, loreotta
