Pure-O/Fear of Earth's Curvature

Hey! So, I've posted a few times on this website about some things that bother me here and there but I'm just gonna post again because I've been in a rough spot for a couple months now and it's always nice to hear some input from others who are similar. I've had very deep existential thoughts my whole life that I've learned to cope with, however this one for some reason has been the hardest to push through. I've never heard of anyone with the same obsessive thought/fear, but basically the most simple way to put it is that I get freaked out by the thought of the Earth's curvature. When I'm in small spaces it isn't as bad, but when I think about the other side of the world and how they are completely opposite from us I get so freaked out. I usually love going on road trips but now It's hard to enjoy it because I can't stop thinking about how I'm curving with the Earth as I drive instead of just enjoying the vast scenery around me (which I typically love). I'm pretty sure no one (or not many) thinks that deeply into their surroundings as much as I do, and it gets pretty distressing when I'm just trying to enjoy my day but I can't stop going in thought circles to make sure that I'm not going crazy. I've 100% recovered from this before which is a good sign, and I even took an astronomy class my first semester at school and I never got nervous or obsessive about anything which was such a liberating experience. However, this recent setback is so discouraging because I worry that for the rest of my life I will just keep going up and down and never fully get through this distressing obsession. When it gets really bad, I feel like I'm not human and don't belong in this universe if something as simple as acknowledging our planet's shape scares me. Anyways, I hope some of you can empathize with these thoughts and feeling and I would love to get some input on how to get through this rough patch once again! Thank you all so much!!!

good on you for taking an astronomy class. ballsy.

i understand this theme. there are times i obsess over how deep the ocean is and i completely freak out. it is so deep. so dark! what else can be going on down there?! i also obsess over infants developing inside the womb. thinking about a human body being able to construct another person's rib-cage is just too bizarre for me to comprehend.

i have boiled it down to control. for me, at least. the examples mentioned are in the hands of the universe, time, space and science. i couldn't attempt to control any of them if i tried, hence the rumination.

our obsessions are mostly surface stuff, so try and pinpoint what else is going on in that moment. any stress you are overlooking, any issues you are shoving aside. you overcame this before so you know you can do it again. good luck.
