Who else doesnt sleep anymore?

I started yr 11 this month, and cause i want grades 7-9 in most my subjects I'm at 4-6 I low-key do not sleep anymore. The way revision has consumed my life.

I will come back from school exhausted, take a nap, wake up at 9pm, then revise all night. Probably get 1-3 hours of sleep, before repeating that cycle.
