Yeah, both medical doctors and mental health professionals can be obnoxious in their own way, and psychiatrists are in both of those categories.

I'd say you should be forgiving of the following things:

Recommending a drug in the same class as something else that was no good for you. It's pretty common for people to get benefit from one drug when a really similar drug was ineffective or had bad side effects. Heck, in some cases, people can get horrible results or great results from the same drug depending on the details of how they take it (dose, dose frequency, extended-release versus instant-release pills, time of day you take it, whether you take it on an empty stomach, etc.). Granted, I don't know which class of drug you're talking about, or what you're being treated for, so maybe I'd agree with you that it's nuts if I were more aware of the situation.

Recommending a drug that potentially has unacceptable side effects or interactions with other drugs. Again, I don't know which drug you're talking about, so maybe I'd agree it was absurd. All drugs potentially have horrible results. (Example: Amphetamine is intended to treat cognitive impairment caused by ADHD, is often used off-label to treat cognitive impairment caused by other things, and is often used by people without impairments as a cognitive enhancer... but it still potentially causes cognitive impairment.) Generally, the really bad effects only happen with a small number of people, otherwise the med would be too unpopular to be on the market and often the government won't approve it. Unfortunately, it's hard to know whether a med will be good for you before trying it.

Having no idea what certain meds will cost for you and needing you to provide that information. It actually isn't their job. I can still understand your frustration about it though. Insurance and medical billing is so confusing from the patient's point of view, and even if it's easy to get that information, even easy tasks are a pain for people dealing with untreated mental illness. I wonder if some of the psychiatrist's office staff might be able to assist?

Saying "okay, best of luck" when you fired her. That's probably the least bad thing for her to say. It's not like she should argue with you or anything.

Asking you a bunch of questions about your circumstances, history, etc. in an intake appointment before prescribing anything. I get the impression psychiatrists generally want to re-evaluate you rather than trusting the diagnoses of your previous providers, especially if the previous provider was a general practitioner or not even a medical doctor at all. (Therapists are trained in psychology, not psychiatry, so I think it'd be fairly irresponsible for a doctor to treat you based purely on whatever psychiatric diagnostic labels your therapist gave you.) Granted, it's bad that she didn't prescribe anything in that first appointment.
