I'm sorry there's really nothing I can offer with regard to this. But I noticed you had yet to receive a reply to your post. So I thought I would write one. And while I'm certainly familiar with concerns related to being transgender & transitioning, I know little about DID.

Based on what you wrote I wonder if, perhaps, posting this in the Dissociative Disorders forum might get you more replies than posting it here in the LGBTQ+ forum. (I don't really know. But that's just a thought.) And, beyond that, hopefully you're seeing a therapist or a psychologist. Talking with them about your concerns may be another important thing to do. My best wishes to you.
