We are social mammals, our evolution has programmed us to have a strong urge to merge with the social group, to be accepted and have a place in the 'heirarchy' of the community we live in. What you say Dana1010 about humiliation being so powerful, is a testament to this. Being socially outcast or devalued in the eyes of others isn't just 'codependence issues' imho, it hooks into our programmed survival mechanisms and has a big impact on our identity.
We grow up learning to mirror each other too, to have empathy for others, because it is actually beneficial to our survival. We were not evolved/adapted to sole survival. Our entire being has been built to be part of a social group, advantageous to our survival and success in life.
When life deals us a 'devaluing' blow we go to the bottom of the social ladder in our own minds at least and sometimes in actual reality in the eyes of others. It's entirely understandable that survivors of every type of trauma come to view themselves as less important, less useful, less desirable and so on.
Human beings have the added complexity, that apparently other mammals don't, of having a higher level of consciousness that needs to find meaning in their lives beyond their physical survival needs. This is what I believe trauma survivors have a difficult time integrating. Myself included. It is difficult to move forward from trauma, live with the resulting injury and assign meaning to the experience that makes sense of it.
None of us want to feel that we consume the resources of our social group, community, world or what ever it may be that we see ourselves living in. We want to contribute something meaningful and useful. Anthony has done it, he has contributed and designed something quite groundbreaking and who knows where it will lead to? Each and every one of us here on his site is doing that, in ever so little and big ways. For me, that's a good start. Things only get better from there.
