up until my mental health diagnoses, my memory was awesome- I could remember tv skedules, phone numbers, details of songs, as soon as I was diagnosed the memory just started to go
now it's at a place I struggle to remember what I did 5 minits ago (at times), and at times I can listen to music/ watch tv, and don't even remember what I am listening/ watching (even if it's something I really enjoy)

at times though, I do have brilliant memory flashes

a couple of weeks ago I was talking to someone about movies, and movies I used to watch as a kid years ago

well, one thing led to another, and before I knew it, I was describing a movie that i'd watched only once as a kid, and asking what it was called (I'd only watched this once, so it would have been virtually impossible to remember it), and they are like oh, yes, that movie is called such and such

then it stays in my memory for like a second, just enough time for me to write it down- if I don't in say a second, it just goes and all that was for nothing
