I feel like people forget psychiatry is a paradigm we created with flaws and biases of our own and not something divinely decreed by reality . many forms of treatment are designed to profit off people's symptoms ongoingly without finding solutions in a holistic way. not to mention the ableism of how it's diagnosed which often stigmatizes people ("personality disorders") without recognizing the root cause (which is often a response to trauma/survival). Throughout history people have been damaged by treatments seeking to make them more palatable to society rather than improve their quality of life.
also the way that diagnoses are weaponized against patients. "oh, they're a (____), so you can't trust what they have to say." leaving them vulnerable to systematic abuse.
