im completely burnt out and im at my limit

im currently in my senior year of highschool and ive never felt so low and hopeless. From october to december weve had continuous exams, the maximum break in between being 2 days. I had winter break for ten days only to immediately have exams after. I get an average of 4-5 hours of sleep everyday and my mental health is at an all time low. The thing that pisses me off the most is that my school knows how badly this shit affects us, they know we cant study in such a short amount of time and that the pressure is overwhelming and they still have the fucking audacity to walk into class and ask us why we're so tired all the time and why we cant score well. Ive lost interest in anything at all. Im tired 24/7 and i cant focus on anything for more than 20 minutes. I feel so fucking frustrated cause i get pushed beyond what i can achieve. Im happy getting the grades i currently get but my teachers? fuck no. They need me to get perfect scores cause that's whats important right? They dont care if i want to die, they dont care if i physically and mentally cannot achieve it. To them the only purpose of my life is to study study study till i die and rot. Im so fucking tired of breaking down over exams and getting bad grades. All i do anymore is cry, cry till i physically cannot anymore and i dont know how much longer i can take it cause im going crazy.
