Ol' CS:
Your description is a good one. Mine came along with anxiety, too; the only description I can give it is as "my own private vision of Hell" - nothing but hopelessness and terror as far as the eye can see. I never want to go there again. I'm taking way too many pills, but the ones for depression and the ones for PD have got to stay.

To get back to rd42's original question, I understand that there are some PWP's who have had no depression at all, and more that experienced it only the first few months after diagnosis. More than 50%, though, do experience some depression of more than a few weeks duration.
