i know its not a huge thing for alot of people, but i just did 3 70+ hour weeks in a row and i feel a little bit crazy. i feel like when i close my eyes i can see my computer screen. i feel tired all the time, and a bit like i want to throw my computer on the floor, and i think i might be hearing things and seeing colours. also i constantly feel like i'm running out of time to do things, like there's this huge egg timer in the background. any advices?
