I've known people that were helped by meds, and people that weren't, so I'm generally willing to accept "X was a bad idea for Y person" in a story as long as it's not clearly part of a crusade against medication or something like that. I hate Stories With Morals regardless of whether or not I agree with them. It'd definitely be nice if more people knew what they were writing about.

(FYI antipsychotics are occasionally used to treat some kinds of psychotic depression, but IIRC it's not at all common - I wonder if there's some real media source somewhere that uses that and that's where people get the idea they're used that way?)
