I've been having an "all over negative feeling", and I can't tell whether it's the Parkinson's, depression, anxiety, a combination of two or all three of these causes, or something else. It's as if my brain is feeling increasingly burdened by the rest of my body.
It may just be a continuation and redefinition of the "mind-fog" that I get during down periods. Also, I've managed to alienate my "support group", so more fear is added to the mix.
Isn't it wonderful how this disease takes over one's life? It's a powerful lesson in humility.
