Luce,
That makes a lot of sense. I am at Coorganizer of a DID (non-therapy) group and we often talk about how we would create our own therapy that would work. Unfortunately none of us seem to be able to stick with it when we all have so many alters but it sure does have merit. I agree with you about the alters perceptions and experiences of the abuse. And finding someone who will hear it and not freak out – that is key.
I find that I feel silly when trying to explain these things to people because I can read their body language and see the disbelief in their eyes. Perhaps going in to it with exactly what you said would help, just to say I don't need you to fix this I just need you to listen and suspend your disbelief. And then we can heal ourselves.
In fact, talking to one of my specialists are doctors about a abusive interject self helped me understand more about who that individual actually is even though it was terribly embarrassing for me to Diebold the information and now have it be part of my record. Perhaps now that I know more I can work with that altar.
Thanks for your post!
