I don't know your pdoc, but from my experience with pdoc's (and all doctors really) she probably is arrogant and short-sighted, but I doubt she's actually scheming.

She's arrogant because she's afraid to admit to anyone, including herself, that she doesn't really know what she's doing. She's just doing the best she can and hoping for the best.

She's short-sighted because she operates in a system that won't allow anything else. Time and patience aren't allowed. The push is for results - and as fast as possible.

The sense that she's scheming may come from the habit of mental health professionals to assume that their patients aren't competent to be full partners in their own health care. So decisions are made behind their backs then pressed on them. It must feel very creepy from the point of view of the patient. Also it's a terrible thing to do to someone who's already paranoid.
