If your Pdoc wants to switch around medicines, I think it's a good idea. You seem to be suffering symptoms of paranoia either from untreated symptoms or perhaps even side effects of the medication.

My grandfather complained for months about bugs being in his house before he was finally hospitalized for hallucinations and we learned that his parkinson meds he started so many months ago were causing them.

Of course, PLEASE don't quit your meds thinking that they're making you feel this way, but I also think it's a reason to be more open to medication changes. With a few tweaks here and there, my grandpa's parkinsons is doing a lot better, without the anxiety!
