Psychiatrist prescribe you drugs according to a subjective classification based on DSM or ICD. The point of psychiatry is to mislead healthy but vulnerable people into believing they have an biological disease, prescribe them drugs that don't improve people's wellbeing in the long term, and make big pharma even richer. Read Loren Mosher letter of resignation. There's no point in psychiatry other than 1. exploring vulnerable people, 2. diagnosing healthy people with "diseases" so they can get disability income. It's the easiest job in medical field because it's not an actual medical science. Psychiatrists are people who found actual medicine and medical science too hard but want to explore people for easy money anyway.
Despite effort from neuroscience, there's no objective and empirical scientific validation (e.g. biomarkers) for any psychiatric classification. What evidence shows is the causes linked to psychosocialeconomic issues, and no biological/diseases process has been found by scientific community. That is, the evidence points towards psychiatric diagnoses NOT being biological disease, so the use of biomedical intervention like psych drugs is also wrong in the disease centered model of psychiatry.
