Part of me wonders if this a worldview that flourishes in isolation (seems to have worked that way for Lovecraft)
i know they seem like malignant monstrosities but black people are actually quite nice when you get to know them pompey
personally i'm very atheist and rational but i'm also genuinely stimulated by shit like books and games and movies and sports and various other hobbies, and that may not be rational at base, i think it's more of just a brain wiring thing, like OCD or something. i go out with friends having what would conventionally be considered a great time and i'm like ugh i wish i was at home browsing fucking criticker lol. i guess i personally feel that hedonism follows just as logically from atheism as despair does, 'cept my brand of hedonism is dorkier than most people's. i also think feeling like basically everything is retarded and meaningless and hollow actually works in my favour because it means i don't pressure myself into being a Real Person and doing stuff other people consider to be 'living' or whatever, i don't really have that grass-is-greener feeling that stops me from enjoying my unambitious boring-seeming nerdy existence. i do tend to set myself goals though, even ones as trivial as completing a list or something - i get antsy if i don't create some sense of purpose and direction for myself, artificial though it may be (isn't it always?).
that said, i HAVE gone through spells of feeling like you do in the past, and incidentally the worst of those spells came after a trip to america that highlighted a lot of things i didn't realise was missing in my life, so i do think i can empathise here. i think it helps at those times to have companionship or to be working toward some more conventionally meaningful life goals or whatever. having a girlfriend or doing studies or following a career path or, yknow, that kinda stuff. it's not that it changes your worldview so much as makes it easier to bear/ignore if you have something concrete to aim toward or people to share your life with. i doubt these kinds of ideologies seem to matter so much when you aren't spending nearly all your time dwelling on shit by yourself. so i suggest... y'know, the obvious really, working towards moving somewhere with more people and more stuff going on, maybe signing up for some kind of courses or clubs or getting a job that forces you to interact with people your own age etc. i don't know the specifics of your situation and how difficult making that change would be practically speaking, but i'll add that there are an absolute shitload of people out there like you who feel like they haven't lived and don't really know how to act/live like a normal human being, and also plenty of people out there with similar interests - if you lived and worked somewhere more populated i've no doubt you'd meet some people who you can actually feel comfortable being yourself around. i mean, you only went to america for a short time and already met someone who you really connected with, right? i know you're probably still hung up on that specific person, but the point is you probably underestimate how many people out there you'd connect with if you put yourself in a position where you could actually meet more of them. high school is reeeeeeeeally not a good way of judging whether there's a place for you in the world btw, high schoolers are the fucking worst.
