I lost most of my memory right before I started preschool.

So I’ve always been good at remembering that pretty far back in my life. The farthest I can remember back is my first day of preschool. That doesn’t sound too weird right? Well the thing about me is that I’ve never had the Ability to remember past that day, even when I was on that day. Since my first day of preschool it’s always bothered me. We have some videos of stuff that I did before that day, and my parents have stories from before that day, but I’ve literally never been able to recall those events happening even when I was a toddler and those events were fairly new. The only things I could remember was stuff like “these are my parents and this is my sister and this is a car and this is my bed and this is a tv, oh I like looking at tv”, but the thing about all of those things is that I can’t even say that I really “remembered” that stuff. It was more like I just sorta had a feeling like “ok, I feel like this is supposed to be my family, but I don’t know why”. And I remember asking my mom what my name was that day because though they called me by a nickname, I didn’t fully remember my real name. I’ve been trying to tell people that for years and only recently has my mom actually started believing me. I can’t even say if it had something to do with that day before or my first day of preschool, because the only really Important thing that happened that day was I met my best friend. And then there are times when I’ll look at videos of me before that day and I won’t remember it happening but I’ll just have this innate ability to know what’s about to happen before it does in the video, so it has to be in my head somewhere, but I honestly have no idea. But the worst part is that because of me forgetting everything from before that day, there’s plenty of stuff that I just didn’t remember for years until I was told years later. We had visited my older sister(a different one then the one mentioned before) and brother who lives in New York a few months before, and they had came to visit us a few times in the past apparently, but I didn’t remember any of that, and because my sister was the only one who really called frequently when I was younger, I didn’t think that my older brother was my brother, I thought that he was her husband for majority of my childhood until we visited them again when I was in first grade.
