I talked to my T about this the other day. I told him I don't know why anyone would admit to having a NPD (or a BPD, for that matter). The information that is available to the general public makes them sound like horrible people (I hope it's okay to say that, seeing as how I probably do suffer from the disorders), and there is not one good quality in that diagnosis. But, are there really any good qualities to any mental health diagnosis? Actually, bipolar might be one of the few. There is a lot of good in the ups they can have, the creativity, etc... but, the downs sound like they really suck.
Anyway, that is just a huge flaw I see in psychology. They need to come up with some positives for those of us who suffer from certain disorders.

I also identify as an INTJ... not many people like us... we're very aloof, for one thing.. but, do a few internet searches and you can find a multitude of benefits from having the INTJ personality type. With tips to make it work to your advantage... not so with NPD. I defy you to tell me one positive thing that comes from having NPD, or tell me one tip to help make having NPD work to my advantage.

So, I identify as being INTJ.. I am INTJ... but, I also may have some NPD traits (along with BPD traits).

It was encouraging to read this thread... And see that some Pdocs seem to understand NPD and how to help those who suffer from the disorder.
