I don't have any parts that admit to being abused; I do have several that carried the hurt for ages and ages. Part of being dissociative for me is that I don't have to remember the abuse, and parts of me think that is a good thing. That's why I have parts-to not remember (and be overwhelmed) by feelings. So for me to have little glimpses into my past without emotion is common.

and I have no idea who I am. T3 says she is treating "me" but I have no clue who that is. I could probably create another part to cope with therapy and memories

As far as communication between parts, I started slowly. For me, journaling was very helpful. Several times a day I would sit down and see if anybody wanted to write. They could identify themselves or not. It was interesting to see the different handwriting. Really remarkable. And some parts don't know how to spell. That helped me start to accept that perhaps I have DID.

I am now stable (thank God) and am working on the processing trauma part of DID treatment. I do not have the goal of becoming one. My goal is to function well IRL. If that involves parts integrating, that is fine with me. If not, that is ok also. For me, deciding that everyone is going to integrate is just anxiety producing and doesn't help me function at all. Having said that, there are a few parts of me that do function together all the time now. They have the same opinions, thoughts, and feelings. I still call them by both names, but I would consider them integrated, at least with each other.
