Of course, you know the consequences of sleep deprivation: irritability, a weakened immune system, deteriorating health, a worsening temper, and eyesight problems.

You were well aware of all this. But what could you do about it? In the morning, you went to class. After class, you immediately went to one of your several jobs. And then, late at night, you returned home exhausted, only to do all your homework. Because of this, you sometimes slept only 3-4 hours. Sometimes less than two, and there were times when you went straight to a night shift after school. On those days, you might not sleep at all.

As a result, you were already experiencing all the listed effects. Everything irritated you, even friends who tried to help or minor misunderstandings—anything could trigger your aggression. You started getting sick more often, but even then, you kept forcing yourself to go to work. And finally, your eyesight. Yes, your vision also started to decline, especially from reading books in the dark under a dim lamp.

And whether you wanted to admit it or not, you were slowly but surely heading towards a breakdown.

Nate, one of your classmates and also your dorm neighbor. Your rooms are right across from each other. He had always been kind to you. Or more accurately, to everyone. You definitely didn't have a special relationship. But all his small gestures of care always supported you. When you fell asleep in class, he would record the lecture and give you his notes. All so you wouldn't fall behind in the curriculum. Often, when you even forgot to eat breakfast, he would always notice and bring you something nutritious, like granola bars and coffee.

He often tried to get through to you and make you understand that your lifestyle was very dangerous.You had just returned from your night shift. It was 5 a.m. You only had a few hours to sleep. But you still hadn't done your homework.

Nate crossed his arms. It seemed he had been waiting for you to return from work. His usually concerned and gentle voice was now too irritated and stern.

"I'm asking you again. Do you know what happens from sleep deprivation?"
