Intense Dissociative Experience

I had an intense dissociative experience a couple of weeks ago, and I would like to share my experience and see what people with diagnosed dissociative disorders would make of it.

Leading up to the episode, I was about to share how I was feeling about my dying dad to my boyfriend (yes, probably the trigger). As I tried to though, I started feeling the normal "pull" I feel of different opinions and different directions. I tried to explain this sensation to my boyfriend because it feels like it's always plagued me. Finally, I said something like "I mean...sometimes I wonder if I actually have something like DID".

As soon as I sad that, I immediately started crying in a way that felt very raw and deep. Over the next 30 minutes or so, I was all over the place, wanting to say so many things; there were parts of me that wanted to believe it, parts that denied it and said I was faking or acting stupid. My boyfriend had the idea to record me in this state. After maybe 20-30 minutes, a distinct part or alter of me "took over".

This alter or part was very confident that we had DID or at least something like it and began to excitedly share information about DID to my boyfriend. He continued to front for several hours and was excited to experience the world. During this time, my boyfriend said he knew I wasn't faking because I legitimately seemed like a completely different person to him. He said I was saying things I've never said in ways I've never spoken, my personality seemed completely different, mannerisms, gestures, etc.

"I" sort of felt like I was in the passenger seat this whole time. The alter or part that was fronting was nervous to be left alone, but eventually my boyfriend had to go to sleep. I ended up feeling a third part and the entire next day felt very strongly like a "we". I felt like the old "me" didn't even exist as out of the three separate parts I could feel, none felt like the old me.

This continued up until my therapy session with my old therapist. We were excited to share the experience but he took it horribly. He denied the existence of DID, made fun of me for suggesting I might have it, mocked me, kept saying "YOU ARE ONE PERSON YOU ARE ONE PERSON" until it began to echo in my head. By the end of the session, I agreed with him and I was back to feeling "normal" like one person like I did before any of this happened.

I've since started seeing a new therapist who had me take an assessment. I only showed abnormal in the "Identity Confusion" category, as I hadn't experienced other symptoms like amnesia. In general I'm having a hard time processing my experience. Part of me thinks something like DID makes a lot of sense but part of me think there's no way. And the amount I feel one way or another depends on the day or even the hour.

I know this is not the place for a diagnosis, but I wanted to see what people thought of my experience. Perhaps there are people who relate to this as maybe the beginning of discovering a system, or perhaps people see it as a one-time anomaly. Regardless, I would appreciate others' thoughts.
