Hello ranae, and welcome to SR.
I'm sorry to hear that your Dad and his disease is causing you so much pain. I'm glad you
found us, this is definetly the place for people like us. If you check out the "Friends and
Family" forum you'll find a lot of information and suggestions on how to deal with the kind of problems you're talking about. You'll find a lot of us have the same feeling and emotional pain that you do, so you are definetly "normal" around here :-)
Welcome again.
Mike :-)
