fade away says my other personality

I wonder how I was like in high school? Or in middle school? Or in elementary school? I don’t even remember anymore; I let memories fade and try to hold on to others. Yet in the end, it seems like they are all fading away.
I also wonder if I have multiple personalities? That would explain alot, wouldn’t it?
Of course, I also think that I’m disfigured (tech. I am with my eye problem) or that I am actually mentally retarded.
