If you hadn't been diagnosed, would the behaviours the psychiatrist deemed "narcissistic" not exist in you? Behaviours don't suddenly manifest upon diagnosis. Diagnoses are a way of pathologising and, ultimately, punishing differences, especially ones which are contrary to capitalist productivity. Diagnoses are definitely not objective assessments of dysfunction: see, for obvious examples, the hysteria diagnosis, the now nonexistent diagnosis of homosexuality/homophilia, or the entirely bullshit racist diagnosis of oppositional defiant disorder (diagnosed as ADHD in white boys, of course). Even taken at their most benign and apolitical, diagnoses are still human-made categorisations of observed behaviour. The vast majority of psychiatric diagnoses describe a set of commonly co-occuring symptoms, not a root cause or a particular structural anomaly in the brain; they aren't any more of a natural discrete category than creating a category of white people with blonde hair and blue eyes, since those symptoms tend to co-occur.
