Is it possible I am an empty system? (Idk how to word it, flair this, and I certainly don’t know where I can ask this other than here)

So when I was young, maybe around 6-7, everytime I got in trouble for something I didn’t remember doing I’d blame it on “the other [deadname]”. No one believed me and everytime it happened my dad would yell at me. Eventually I stopped blaming it on “the other [deadname]”, it’s not like I was blaming some other kid in my school, no other kid looked like me, and certainly wasn’t named my deadname. I always felt like I wasn’t fully one hundred percent whole in my mind, but me feels whole. It feels like there’s supposed to be someone there. Idk is this just my brain being stupid and making me feel fake bs? I understand if this gets taken down but I would like to know if there’s somewhere else I can post this?
