There is a school of thought promoted by Judith Herman and others, called Complex Post Traumatic Stess Disorder. It is an umbrella term that serves to bring together a number of now separate "diagnoses" under a more complete theory of varying effects severe trauma can have on people. Of course, no one person will have them all, but it is meant to show the linkages. It inlcudes the spectrum of dissociation and related disorders, depersonalization, derealization, borderline traits, eating disorders, self-injury and other acting out behaviors, as well as the post traumatic symptoms. I'm sure i've missed a few others, as well, because I'm relating this right now off the top of my head. Okay, it's another label, but what i like about it is that it tried to show the complexity of traumatic reactions and that is great overlap between these seaprate diagnoses. In a way, it kind of dilutes them so that no partcular label becomes an "identity" in and of itself. Also, I think it tends to encourage the thinking that whatever ways we cope, we are more alike than different and that is bound to foster greater acceptance and less stigma for many people who now feel on the fringes of life.
Just my thoughts about it, and something to ponder.
My best to all ...
