You know what? I think I have heard about that ego state thing. It reminds me of psychosynthesis, which my T just told me about this summer. Have you heard of that?
I tend to agree with the idea that borderline is a trauma-related disorder. And I think it would be good for people diagnosed with borderline to have it considered as such, because it might reduce the stigma attached. From what I've read, it sounds like borderline often involves a similar idea to the ego states thing you're talking about, as well as dissociation for some people. I think some people would probably diagnose me as borderline, and I know that what you said about the continuum rings true to me. I'm far from being a multiple, but I am defintely somewhat fragmented. And I am dissociative, a LOT.

Sounds like you've done some interesting studying, and right in the same vein as my interests. (I'm a psych student, and I'm planning on specializing in trauma once I get to a PhD program).
