I only discovered the theory of Quantum Immortality recently, like a few days ago recently, but it's completely changed how I'm viewing my past.
I know of two times I almost certainly died and switched timelines, and the first one was when I was twelve. In this time line my mother saved me and I recovered just fine; but by switching timelines it completely changed my relationship with my mom.
When I was a little kid, my mother was physically abusive. She's even admitted to it a few times, saying how meeting my stepdad made her a better mother and helped her to reign in her temper. But as an adult she stands ten toes down and insists it never happened and she has no memory of it.
But I have very clear memories of being hit. I remember being dragged into a bathroom by my leg to be hit with a hairbrush. I remember being slapped for "talking back" when really my mom was just overwhelmed and overstimulated and lashed out.
And as a child I was *terrified* of her. I would break down into tears if I sensed any adult was upset with me, because I thought I would be beaten if my mother found out.
But now that I'm grown and in treatment for CPTSD, my mother insists she doesn't remember any of this.
Even when I was a teenager and I would flinch during arguments, she would get annoyed and insist she's never laid a hand on me and I have no reason to be afraid of her.
But the thing is, I stopped getting beat after the incident. She never raised a hand to me after that. I thought it was because she felt bad, or maybe I'd gotten big enough she knew there was a chance I'd fight back.
But now I'm thinking, maybe she's not lying.
Maybe she really doesn't remember. Maybe she doesn't remember because in THIS timeline, she never did beat me.
Or maybe I'm just in denial, and this is all part of the treatment journey to fix my brain.
