Yea I can understand that you need to re-experience it in some way. I have DID and a few DID professionals told me and a past therapist that in therapy for DID re-experiencing the situation while remaining mentally aware (emotionally connected to the situation) is called the process of co-consciousness and integration for people that have separated pieces of memories that they are acting out unconsciously. I have gone though this process a few times and am attempting to go through it again for a specific memory that I have nightmares and flashbacks about.

Hang in there it will happen for you.
