BUT...the nature of the beast being as such, Big D thinks the diagnosis is wrong.
Today he put Borderline Personality Disorder in front of me and we read the list. Yes, he fits every single criteria, every single thing that is listed he's either been through, thought like, acted like, or is currently going through.
I agreed that BPD when read on the diagnostic criteria does fit with him, but it doesn't answer all of his behaviour like NPD does.
He wanted an example.
It was difficult to do as I've not researched BPD at all and don't know how it plays out in everyday living.
As BPD says "reckless driving" and he says that's what he does. I had to explain he's not exactly 'reckless', at least not while I'm with him, but he is an arrogant driver, and to a certain extent, yes, there is a reckless element. But mostly he drives as if he owns the road, all other drivers are total idiots and not worthy of turning in front of him, or worth giving way to. He's abusive towards others to the extent that they've done nothing wrong and he's giving them the finger out the window anyway. He glares at every single other driver when he drives past them. He tells me he abuses other drivers through his anger. But I think and told him that I thought it was too frequent for anger, it was arrogance, and if it is truly anger, then he shouldn't be on the road at all.
Anyway, I digress, but this was the only example I could think of at the spur of the moment.
I was wondering if anyone who is familiar with BPD and NPD would be able to cite some examples or areas where they differ. Don't worry if you don't think it would fit my circumstance, I'd be able to interpret it into Big D's actions or otherwise.
Oh, as an example, NPD is often presented with depression as well as abusive and controlling behaviour, all of which Big D have. He did attempt suicide once, apparently, but it sounds to me like a pretty weak attempt and it was back in the late 70's. He's not tried it since, although he's presented himself as recent as November last year at a public clinic for suicidal thoughts. I wasn't present when he was interviewed but I got the impression they told him he was wasting their valuable resources...

I've come to the conclusion that Big D is NOT going to fall into the .01% of people who are successful in modifying their overall behaviour patterns so any answers I receive are not to 'help' him see the light. But to rather give me the background knowledge to stand my ground when he questions my reasoning for suggestiong NPD. Although I guess the psych's backup of that should be enough....but anyway, any assistance is gratefully accepted.
TIA.
