Just a thought here...what about letting your alters talk about their selves to your therapist....I could not tell my therapist much about my alters because I was very limited on how much co consciousness I had with the alters...

co consciousness is things like hearing the alters, being aware that the alters exist, being aware of whats going on while the alters are in control, ...and other things too. each person has their own co consciousness abilities, even the alters have their own amount of co consciousness abilities with how much they share with each other and the host (person they live inside of, some locations call the host the core)

but that didnt stop my therapist from discovering who my alters were, what their jobs, purposes, reasons for being was, what their triggers/fears/ traumas were.

she was able to find out these things each time I dissociated and an alter was in control of the body.

sometimes she would ask me questions about my alters and want me to talk with her about my alters. that was so that she could determine how much co consciousness there was between us, how much I knew about the traumas that caused me to become DID, how much I understood about my internal system of alters.

I would get frustrated because I could not tell her, either because I didnt know the answers to her questions or because every time I tried an alter would take control in order to prevent me from telling. (I was programmed not to tell and if I tried this alter would harm me)

I finally told my therapist what was going on, my fears of telling her things and why I couldnt tell her. she put me at ease telling me not to focus so much on trying to do the right thing...telling her about the alters and what happened...focus instead on keeping it simple...if I can talk to her/answer her questions it will happen and if I cant well it will still happen when the alters take control. her questions to me about my alters was more just a formality for assessment purposes.

she also told me healing from DID wasnt contingent on my having knowledge of my internal system. healing would happen as we take care of my symptoms/triggers. As the alters discover I am now an adult capable of handling things on my own, they would naturally integrate with me, I and the alters would become one whole person again.

she was right. the less I worried about doing things right and trying to tell her things, the more she was able to discover about my internal system of alters and why they were there, what their jobs, purposes, reasons for being was...

maybe you are having so much trouble talking with your therapist about your internal system because you are not supposed to be the one to disclose things about your alters. maybe theres someone inside who's job, purpose, reason for being is to regulate how and when things about the internal system of alters is disclosed. if so then theres nothing you can do, like me every time you try you may end up getting stopped by a alter.

maybe you can explain to your therapist what goes on when you try to talk about your alters with her, and maybe you and your therapist can come up with a way in which you can safely disclose a little bit at a time or none at all and let the alters tell her their selves about their self when they take control.
