Yes I think it is all tied in together. Things I have read on DID therapy and EMDR and dissociation all tie it in together too.
And yes disorganized attachment really hinders me in therapy. When I most need support I push away and isolate because that is too vulnerable and experience has taught me that closeness hurts. I am experiencing that push pull thing very intensely right now. The two needs for support and protection are on opposite sides of a very wide divide. One side is howling out in desperation as they are pulled deep into the internal abyss by the others.
