Hallo Max, I really like what you say, and I want to agree with you. I have always willed myself to believe that i will get well, that the neurons are dormant, not dead, that they can regenerate and mend. I am much older than you and have had PD much longer than you, but with minimal amounts of PD medicine - after 11 years plus years of denial, I take 12 mg Requip, 2 of the 25/100 carb/lev pills and 100 mg Amantadine per day, and I take Curcumin and Flax.
But most of all I refuse to give in and give up, and I feel very, very lucky that I have had no depression so I can be jolly and merry and laugh a lot and enjoy life with a limp and a tilt left (fortunately my sympathies are all to the left, it would be all wrong if my body tilted right) and occasional tremor and shuffling. Mindset is medicine.
Good luck and keep hoping and smiling. We will get over this ..................
