I forget.
Joking/not joking aside, a few main things help me. (I'm bad at typing on my phone so I'll correct this/add later, but unironically will forget to reply to the thread if I don't send this now for notifications later)
(1) coming to terms with the fact that knowledge is so freely available online and elsewhere these days means that it feels more okay if the information isn't in my head. I can still find it elsewhere. And so instead of focusing on restoring my memory, I work on figuring out how to find what I want to remember.
(2) just admitting freely my memory is bad has reduced some pressure in social situations, and made it feel easier to rely on my other methods of eg lots of photos with my cell phone, notes scribbled in notebooks, etc, since my people find it less rude and are used to my strategies and my forgettings. (how easy it is to find those notes later is a different question altogether, but the methods are a start).
(3) knowing that my memory loss is partially a result of trauma, PTSD, etc for me has made me reflect on how it has been there to protect me in the past, even if it isn't serving me now to have the same longterm and short term memory losses. And what manifests for me as ADHD is also probably a fair bit due to the same earlier adaptations, need for hypervigilence, etc
Unfortunately medication has only minorly helped memory issues for me, though for some people it can help.
