No, but a lot of people I’ve met and encountered have a similar fear. Usually there’s no way of assuaging said fears as its very very innate and understandable.

I guess I’m not scared cuz I spent a lot of my early adulthood smoking a lot of weed, drinking a lot of alcohol, doing some psychedelics, and participating in various other behaviors in an attempt to forget my somewhat traumatic childhood, in which I was only partially successful at forgetting.

After going to therapy for some time, I realized that traumas cut deeper than memories, and that there wasn’t much to do but move forward with all of it integrated and try and do the best I can. It’s an imperfect answer, but it’s the best I got.

Because of this when I think about the horror of losing my memories, I kind have made peace with that losing memories is likely simply a part of death. Sure there’s the horror of still being alive when it happens, but even if you believe in an afterlife, you likely can’t hold onto every memory of life and your infinite afterlife, right? Unless you become God or something I guess, but then you have every memory of everything and everyone…which is…well probably kind of boring…so you split your consciousness off into other beings and live as other entities to keep things interesting until the end of time when you, as God, die… unless God also transcends time…but I’m meandering a lot at that point.

And yeah…it goes on like that…a kaleidoscopic rubix cube of making memories and forgetting them and fearing loss and accepting impermanence… eventually you come to accept it…until existential dread hits you from time to time, but you eventually get used to that being part of the whole being alive and existing thing too.

Or at least that’s how my insane mind deals with it anyway.
