Personality Disorders: not all bad?

Not at all. The only one I'd consider 'bad' is antisocial personality disorder APD (psychopath). While others, histrionic for instance, can, at times, be quite entertaining to watch (but also very annoying - lol). You've just got to live with it and understand that ppl with PDs have a problem - and in many cases can't help it. That's not a bad thing at all, its who they are. They're being themselves and, in my opinion, that can never be a 'bad' thing. Annoying or unlikable maybe, but not bad. Plus, there are meds that can help w/ some of the side effects of some PDs.
