i knew about some of them my whole life but didn't know they were other parts until i was in my teen years and read things online/met others online who had DID and pieced things together on my own. i wasn't sure it was actually DID since at that point, there were no clear black outs even though the time distortion was really big, and the switching was like a revolving door. but i met them when they decided to introduce themselves and/or heard them talking inside and at one point was able to talk with several of them.

it took a few years to get an accurate diagnosis because for a long time, they all went quiet but then became active again. i was then able to share about them in therapy.

i thought that i was just delusional or something and still have times where i am in denial about it because things can be quiet for a while or more subtle than they were years ago.

i do not know if they all know about each other or who knows who. i only know that i know many of them, or at least bits and pieces of things about of many of them.
