A British physician provides a taxonomy of annoying patients:
GPs used to talk about "heartsink" patients (who make your heart plummet the moment you spot them on your morning list) and a psychiatrist called Groves even split them into four groups (manipulative help-rejecters, self-destructive deniers, entitled demanders, dependent clingers). But there are heartsink doctors too, and when a consultation goes tits up, there are issues on both sides.
I'm pretty sure I'm not #1, and I know I'm not #3 or #4. So either I'm a self-destructive denier or else I'm not an annoying patient at all. Possibly a bit of both.
