anyone else have memory problems?

i know that missing childhood memories is fairly common. but i've also had difficulty remembering parts of my adult life.

not that i stress it really, except in the past couple years i've "met" people who have informed me that we've already met. and not just like at a party and had a fun lil convo, but like met, hung out more than once. sometimes like had sex and more.

more than one of them has been genuinely hurt that i didn't remember them. like at all. and, of course, i feel bad. but anyone else deal with this? is this bpd/cptsd related? and are there ways to work on this?

i imagine some answers will include mindfulness and working on depersonalization. but yeah. it just happened again so thought i'd ask.
