Tollhouse, I liked your responce and I agree with what you said..
Peaches, only a qualified therapist can diagnose DID, but some T's do some inner child work. I would think that the more work you do in therapy, the more clear it will be what your dissociation degree is.
For us, it was an insider coming out and identifying herself and after a couple of sessions with her, our T put alot of pieces together, "interviewed" me and we began the journey of working with insiders and all that is involved with that.
I hope that you will not let the questions get in the way of your healing journey and let things evolve as they do not forcing anything or having any real kind of mind set that you are either "this or that".....in time that will become clear. IMO, the work that goes into healing is more important than the diagnosis.
