I've seen three threads today where various posters have questioned whether or not somebody talked about has some kind of personality disorder because they have behaved badly.
Personality disorders are serious mental health conditions, a lot develop as a result of trauma. Those living with a personality disorder carry horrible stigma about their diagnosis as well as dealing with the symptoms.
All the armchair psychiatrists on here diagnosing a stranger with personality disorders does is increase the stigma. A lot of people are manipulative, attention seeking, insensitive etc without a disorder. Equating those bad behaviours with a PD is just perpetuating stigma.
I've known a lot of people with a diagnosis of a personality disorder, and on the whole they are great people dealing with a lot of problems. Yes, they can have challenging behaviour at times but deserve to live without the extra stigma.
