quite ashamed/in denial?

so - i’m not diagnosed, but i suspect i might have DID or some form of dissociative disorder. i started talking to my therapist about how i feel that there are different people at the front/back of my head, but i’m somehow very ashamed to talk about it further. i feel like i have 5 very distinct people in my head, i can even talk to them. i have a vivid headspace, and very very annoying amnesia gaps pretty much every day, but i have such an internal barrier when it comes to having this conversation with my therapist. i feel like there is so much stigma that i can’t talk about it out loud. have any of you struggled in the same way? how to help it? i’m afraid i won’t get any answers if i’m so paralyzed when it comes to speaking about my internal world
