The concept of forever. Like, true forever, has always scared me. I guess I look to the futurama episode when they keep going so far into the future they "come back around" but it scares me.
I'm terrified of the void, the "end," the degradation of the universe and it's ultimate demise. I know I won't be around for it but I have that knee jerk, wide awake panic attack when thinking about the permanence of that. And even trying to assuage that with the thought of everlasting bliss in heaven seems, once again, scary cause how can you ever comprehend forever. What if it's actually not great, not actually good? I like that the Good Place explored that concept. IDK, just so hard to comprehend. I chalk it up to ultimately our mortal lives can only comprehend something with a beginning and an end, so not having that ultimately throws us off.
It really the last few months also pushed me out of a darker place, truly treat my time as more precious. I guess I see our lives like that futurama episode, we always come back around again, but it's so long in the time space everything is forgotten and it's new (to us) but the "forever" of time has washed away all concept of memory and we relive it again.
