Nancy,
Happy to know your Father is doing well.
I am worried about you,though. As I recently experienced the hospital/family experience, I know the stress that you are under.
You must listen to your body and rest whenever you need too..or want too.
Don't be afraid to use a hospital wheelchair to get you to point A to B.
They saved me from long walks that I would NEVER have been able to walk alone.
You don't have to live at the hospital to be supportive; frankly, your father will get more rest if the room isn't packed with visitors. I know it is hard, and I wanted to be at the hospital every minute,too..but you won't be supportive to your father and/or family, should you happen to end up in the hospital, yourself. I say this because I care about you
Tears are good, relieves stress. Anxiety attacks are not good, so pace yourself.
Make sure you take your meds on time, and try to sleep whenever it is possible.
You and your family are in my prayers..please, take care of you.

Dew
