How do you deal with someone who has Narcissistic Personality Disorder ?

In this case: my brother. Everyone in my family has been be-stricken with some sort of mental illness, at least on my father’s side, and some on my Mother’s side. My luck-of-the-draw is Bipolar, and luckily, with the right meds, it can be somewhat (ha!) manageable. However, that’s profoundly not the case with Narcissistic Personality Disorder. There’s really no acceptable treatment, because inherent to the illness, all the doctors are wrong, all the therapists aren’t smart enough, and all “shrinks” are charlatans.

When he enters the room, he sucks all the oxygen out of the air. He’s done shitty things to all of my family members and I have never heard him apologize. He takes a lot out on me, and it just has to stop. Seriously, he’s soul-less and it’s gotten to the tipping point. I have years worth of “evidence” to how cruel he is, but what’s the point.

I know, I know how harsh this sounds; after all he’s family. But, for the sake of self-preservation, I really feel like trying my hardest to be compassionate is just impairing me emotionally.

Finally, to further complicate it, neither of us are in a position to be moving out any time soon. So, here we are, stuck in this same house, sharing the same resources and basically all I do is work and stay in my room. Even sharing the most basic tidbits with him start him off on one of his grandiose diatribes.

So, if anyone has anything to help me address this suffering, I’d love to hear it?!
