Eh, I doubt my pdoc sometimes (like right now) and it's for no good reason, like I decide she hates me and doesn't believe me and is prescribing me drugs to shut me up despite having 12 years of knowing she would never do that and if she thought I was faking she'd sit me down and say so. Just because she was a little off I have decided all these negative things and questioned her on stupid stuff, including could she please tell me it's ok and she believes me, which she never actually saw. I still think you have very good reason to doubt yours; your meds are WEIRD and that's coming from me, with massively weird meds.

Besides, they are human and if you didn't question you could wind up with some scary things going on.
