No, not at all. I have an exceptional head for facts, but my personal memory is extremely poor and always has been. I file my memories away within months of living them -- lock 'em in the drawer, then lock the door to the office. I'm like the world's shortest book.
I've got maybe a handful of memories from my childhood (if I try really hard, I can remember maybe 15 discrete scenes from 4-17 years old), and while there are a few I always look to wrt my trans history, I've got such a dearth of memories that I'm completely unconvinced it's not all fabrication and reconstruction error. Emotions and desires always cloud recollections, and I know that I want a simple and logical path with which I can trace my gender identity. There's no reason for me to believe I actually have one. Surely, there's some distortion.
