Either that, or they're actually "normal" human functions that are incompatible with society and often cause social disharmony, so they're turned into shame words that make you feel flawed so that you stop behaving that way, although a lot of times I believe the fixation on the label actually exacerbates the behaviors (take a test that says you're INTJ, you might subconsciously behave more like you think an INTJ would sort of thing). Some are even common reactions to society itself (speaking chiefly of depression here), so psychiatry has to abdicate society of responsibility and place it on your brain chemistry.
I've always seen bipolar as a mental struggle against emptiness, for example, rather than its own distinct thing.
If these disorders were true "defects" they would be far too uncommon and unique to assign to broad labels. I'm referring mostly to personality and mood disorders (you are not behaving correctly or feeling correctly, when there is no objectively correct way to behave or feel). Psychotic disorders can cause either intense deviance from or intense realization of the truth, and while both are often unfavorable in a social sense, the former is the only kind you can objectively call a "flaw".
Although I do believe that antipsychotics that have purely antagonistic features are "stop thinking, feeling and seeing so hard" or "stop crossing wires between different parts of your brain that most people don't cross, stop (perhaps unintentionally) experimenting because it can be dangerous to you, us and others" drugs. Some of those thought patterns might be incorrect, some of them might be painfully correct but nobody else notices them. I come from a standpoint where I believe that the mind and brain are much more modular than people let on, and that gaining true control over your cognitive functionality can be disastrous (but also cool) to someone.>>19028106
It was like remembering what living is actually like for a little bit
