thankfully, i've undergone many mental transformations since my first contact with western thought of existentialism. it's terrifying to be 15, wake up one day, and realise so many things at once. to find out how enormous the universe is, how small you are, how it is all so random/unfair/inexplicable/insert any other adjective. but it gets better, it really does.
when i was in high school, i was a very active student in my ethics class. of course, as any other high-schooler, i also had existential crisis (if not crises) going on 4 business days non-stop on average. it was after finishing neon genesis evangelion (duh!) that i came up with the idea of non-physical existence. this thought of leaving my own body per se, and somehow existing somewhere as something purely abstract, was very important for me back then, so naturally i shared my concerns with my teacher (who was amazed to have someone actually listening to her on those monday mornings, and even say something of their own). i was very sceptical to her response for a long time, and basically thought she knew shit. it took me some time to realise she was right.
