I understand totally !!
It sounds like your family likes to tease you just like mine does me. My daughters also act like they know everything ... But then when I am gone they have to call a dozen times. My favorite is when I told Amy to put drops in sammy's right eye.... She called and asked " his right or my right?"
I am really sorry you are going through this....it know how hard it is to see a loved one in pain. What a horrible accident ... Please know you are on our prayer list. I know that prayer list works !!
Please keep us posted.
