Parkinson's

My father had PD for as long as I remember as a child, before he passed away when I was 13. I have reached the grand age of 80 thanks to the great NHS. I suffered with restlessness for many years before the shakes started and I was diagnosed with PD. Now I feel a burden on my wife who does everything for me and I get depressed because of it. Physio does what it can, but nothing seems to improve it.
