so, I was one of these people. for me, it is simply impossible to fall asleep at an earlier time than my circadian rhythm dictates. no matter how tired I am, I lie in bed and cannot sleep. (there are a couple of other factors to this too; but circadian rhythm is the biggest one.)

so I muddled through school on 3-4 hours of sleep, the occasional nap, and slept well through the day on weekends and during holidays. it sorta worked, but in school I was always sleep deprived.

sleep deprivation means impaired cognitive performance. you just can't THINK as well. you can't concentrate. you make lots of careless mistakes. you have no idea what you just read. ADHD adds to this, but it is SO MUCH WORSE on too little sleep.

it's also just plain miserable. I felt, back then, that i would crush my body living like this. I couldn't really put it into words why I thought it, but I estimated that I would make it through uni and then not one step further.

sleep deprivation is torture.

you can feel your body breaking down bit by bit. you try to think and you can FEEL your thoughts getting stuck and disintegrating. all you want to do is get some blessed shut-eye. everything weighs you down. every little annoyance just crushes your nerves.

at the same time, you're not allowed to complain. it's your fault, after all.

this is not a way to live.

I knew this then, but I could always catch up on sleep debt. I had no idea how much worse it could get

Uni was comparatively easy.

I simply... didn't go.

I invested a few days into studying before each exam and that was that. the lectures that you were forced to attend were few and far between. it was fine.

I still crashed a few times. I had to work student jobs to stay alive, and I had to get up early for them. at one point I dropped all of my jobs and once, crawled in bed and just slept for a few weeks.

I already felt that I was breaking myself

then, ultimately, I made it to my bachelor's thesis and got a job in some company and wrote my thesis and once that was done I transitioned into a 40-hour work week.

and i crumbled.

everyone, including doctors, kept telling me that it was fine. the sleep will even itself out. you'll get used to it. once your body is lacking sleep, you will automatically sleep earlier.

can't sleep? just go to bed earlier.

tired? take some iron pills

no, don't take any naps, it will ruin your sleep pattern

it got so bad that I got seriously suicidal. because I just wanted to fucking sleep. there was nothing else going on in my life that was stressing me. my entire life was only my job, and my sleep deprivation. there was nothing else.

but everyone kept telling me it's normal! but after a few months your body gets used to it!

no, it fucking doesn't. if your body has a hard, immovable circadian rhythm, it will NOT MOVE.
