The thing about memories is, I have very few of them. My memory doesn't extend past the previous day, and sometimes it's even just a few hours. (My sister asked me the other day what I'd had for dinner the previous night, and I had to struggle to come up with it.)
I had 9 months of electroconvulsive therapy (ECT), in an attempt to get out of the most severe, longest-lasting depressive episode of my life. I got 2.5 months of peace before I ended up in the hospital, actively suicidal. Not only did it not work on my depression, it fried my brain. People tell me things, or show me artifacts from places we went together, and I just don't remember.
It's troublesome with work, too. Even if I've done something several times, if there's been a gap since the last time I did it, I'll have to ask to be shown again. It pisses off my boss. Last time, between the time I asked him to help me and the time he responded, I remembered how. But it took me several hours to surface the memory. I know he's busy and he relies on me to do stuff he doesn't have time for, but I can only do what I can do. I try my best in the face of my limitations. The fact is, they're not going away, ever. It frustrates me, too. But I took a crapshoot with my brain and I lost. It's something I'll have to deal with for the rest of my life. If anybody has any ideas for ways around it, let me know.
