Infinite alternate universes exist.
Countless, stretching out like reflections in mirrors placed across from one another.
They reflect, but they refract, each subtly different. In them every action, choice or change, occurs every possible way. If something can happen, then in some universe it did.
And every choice you ever made, you could possibly make, you make, and don‘t make, and never get the chance to make. And everything you could want to be or have you already have and are, somewhere in this infinite web of universes.
So calm the fuck down. Your problems aren’t a big deal.
