Will I die cuz of my routine or what😭 😭??

My sleep schedule is uhm, well, chain utar gayi papa 🫡subeh ke 4:30 baje soti hu aur 9 baje uuth jaati hu. My hands are sore due to writing so much shit throughout the day and my legs hurt cuz i sit on my desk all day and night and only move to eat and for a minute or two in a while. They're hurting as im writing this. Ive been doing this for almost 3 weeks now continuously bas beench me ek do din so jaati 12 baje bhagwaan ki kripa se. Im VERYYYYY anxious abt my boards even though i got good marks in my pb. I keep on solving questions of the same chapters cuz I feel anxious abt them and Im way too scared abt my exams. HELPPPPP
not to mention my sleep was no better during 9th cuz of coaching +school all together, i used to get home at 7 PM direct after school :\ But atleast i used to sleep at 2, now its 4:30 and i think its only gonna get worse until boards are over. I will fix this in 11th for sure.
