Hi brain, Gosh I know you are upset on top of your own pain, with your dad. If I had PD or was suffering I would contact this gent up in canada named bob dawson. PM him. He has PD, and has to be one of the most compassion men I have met on this site. He has great knowledge of PD and may be able to offer advice. Hug your dad hard, it is so hard to feel and know your own deteriation is at hand. That is why your dad is crying. I wish I could hug your whole family. ginnie
