To whoever needs to hear this: you're right, it is wild that it takes you so much effort to sleep and no, that's not just the way sleep is. Things like mental health and screen usage do have a massive impact on your sleep, but it's a misassumption to work on this belief that a 9-to-5 schedule is some human default. It's a new concept brought on by the Industrial Revolution. There's neither some fundamental flaw with you if you can't function on that schedule, nor is humanity being overrun by insomniacs if most of those people seem to be sleeping just fine on weekends. That's just natural variation in circadian rhythms, buddy! And the lack of flexibility for that is destroying both individuals and the precious productivity that the capitalist structures upholding this tradition holds dear.
