Welcome aboard!
Amnesia has been very different for me through time. As a kid I would completely blackout, completely forget a type of situation when being in another type of situation (forget about home when at my grandparents', forget about school once home...)
As a teenager, it was specifically my social memory that was a mess. At this time of my life the main host was a trauma holder so I would spend a lot of my days in flashbacks while forgetting about the people around me at school. Then suddently I would "zone back in", remember the people and the bad things they did while forgetting about home entierly. People would make fun of me and ask me questions and laugh that I was unable to answer due to the blackouts.
Adult and pre therapy it kept going with similar vibes: forgetting about a context while in another context, forgetting about people... all the while having all the micro amnesia of ADHD of course (why not both?

)
With therapy and integration I now have all my ressources shared across all my parts/identities, same with autobiographic memories (except for the last crumbs here and there that still need to be found and integrated) and I no longer fit the diagnosis criteria for any dissociative or traumatic disorder. I still have work to do in order for things to be perfect (maladapted behaviors to unlearn, the last open wounds to heal, staying grounded still requires a bit of effort...) but the symptoms are under the thresehold of diagnosis so according to the books, I'm healed.
I'll still have the ADHD micro amnesia though coz that's something genetic for me. But all the tools I developped to compensate for the huge dissociative amnesia are helpful and so ingrained in my habits that I cope well enough.
