One of the worst parts about not sleeping enough over a long period of time is how divorced from reality that level of exhaustion can make you feel. Going without any sleep can rapidly turn bad, making you more susceptible to getting sick or even causing you to hallucinate if you go long enough without just collapsing. Definitely not going to deny how awful all that can be or imply that just being chronically short on sleep is worse than getting zero sleep. I think it’s just a different kind of hell, though. One that varies based on how much sleep you’re missing out on, as compared to what you need to feel functional.
