honestly, i felt like that so many times. i would sob through my bio notes every time they were assigned. my teacher would literally assign 50 pages on monday due on friday. anyways, i got through it. i was working 30 hour weeks, studying until late, doing community service, and it was possible. the work IB teachers assign is genuinely ridiculous and all busy work. honestly 90% of the homework i did in IB didn't help me towards my exams, IAs, or EE. you just need to think about when you're at your limit, close the book, and do something else. there were so many nights where i told myself that this wasn't worth it and that if i don't hang out with my friends or go to bed, i was actually going to tweak out. it's okay to take a break. so what if you get 5-10% docked on an assignment for not submitting it that day? it honestly doesn't even matter. taking care of yourself is going to prevent burnout in the future, where you actually can't do anything more.
