Frank,
Welcome to Healing Well. Glad you found us.
I can't answer all your questions. I can only share my experiences. I was diagnosed in 2001 and had symptoms 2-3 years before - that's 15 years. I still work full-time and do everything I ever did... maybe with a bit of a shake or a little slower. My prorities have changed - things that seemed important like a neat and tidy house (OK, I never have had a neat and tidy house) ... are less important - time with family is important. My sense of urgency has changed - I'm doing things now that I might otherwise have done later like traveling.
You mention finanical issues. It is true that your earning years may be less. I'm confused about where you live, but if the US you'll want to become educated on things like disability and social security. You may want to be more conservative financially. I don't know if you are selling your house because of your PD, but only you know your situation and what your comfort level is financially.
For me personally, I had to fight back. I did that by getting involved in many PD organizations, etc. The biggest way I fight back today is by rigorous exercise. I participate in a non-contact, boxing-based fitness program for people with Parkinson's - and I believe it has made a difference. I believe it has slowed my progresion, kept me more agile, fit, etc. I would really encourage you to exercise - rigorous exercise. Force yourself to do more than you think you can - it's called 'forced exercise'.
More than anything is attitude. Will your life change? Yes. Will it affect your loved ones? Yes. Did you want to be in this (PD) 'club'? No. But you are. Are there worse things? You betcha. I can only hope that the funding and research will continue to improve medications to address the symptoms and that one day - in time for you and me - there will be a cure. I would encourage you to find a support group. It could be online or in person. I'd look for a young onset group or check out the national PD websites to see if they have info on a young onset PD support group in your area. Sometimes the 'regular' support groups can be a bit overwhelming to someone newly-diagnosed.
Best of luck and keep us posted. Hopefully others will share their thoughts and experiences.
