I think Western is right, you must remain positive and keep your sense of humour. 3 years after diagnosis, I have not changed too much. Initially I suffered many of the symptoms you read about. They would last a few days and then disappear, as if to give me a taste of things to come. Now my main complaint is exhaustion, but even that is improving so I maintain a positive attitude.
I ain't afraid of no parkinson's!
About 5 months after diagnosis, I started to find some humour in my condition and decided to start a blog ( you can find it at www.wpgchap.blogspot.ca) in which I detailed the good and the bad. As I re-read some of my earliest entries, up to today's, I can see the good times outnumber the bad and although the condition is no doubt continuing to progress, I concluded long ago that it is not as bad as I thought it would be. Of course, I got it at an age when it is most likely to occur. I probably would not be so cavalier if I had been diagnosed with early onset.
But remaining positive, finding humour and exercising I believe, can slow the progression for everyone.
Don't let it beat you by letting it get you down.
