In my case there was this guy who spent a year trying to convince me I suffered from a specific personality disorder. At one point I was feeling so vulnerable I started considering whether he might be right even though I knew at a rational level that he wasn’t (after almost 30 years of seeing psychologists and pdocs somehow not noticing anything). I talked to the people who know me the best, including my ex, and they all thought he must be trolling or just being malicious. Eventually I discussed it at some length with my pdoc who was quite categorical that the whole personality disorder was complete bs. To my shame, and a perhaps a testimony to how sz can impact cognition, it took me a full year to realise that projection, a desire for control, and resentment were at the root of his behaviour, coupled with an extraordinary degree of blindness regarding people’s mental states (including his own) amounting perhaps to a partial, yet still fairly severe, case of dunning kruger syndrome. I guess some people are just bad seeds.
I know, SZ diagnosees, especially those suffering with paranoia, don’t make very reliable witnesses but still… has anyone outside the medical profession ever tried to convince that you suffered from a mental disorder that you did not?
