this is hard and i feel like i and a lot of people go through feelings like that often i ended up not finishing the buttload of homework and studying i had to do over the weekend and its a terrible feeling to be fair my ap art history teacher told us to study almost 80 different pieces and i had to study for a unit exam for pre-ap chem i know i couldve accomplished a lot more if i wasnt so useless and it makes me feel like garbage  maybe if youre staying up doing nothing and you see this try to make a schedule of what you want to work on and when - and make sure to plan breaks - and use a timer to try to keep yourself on track thats what seems to work best for me and tbh i really should be doing it more too  keep your chin up you can get through this maybe put enough time aside to take care of your interests but whatever you do your mental health comes first so try to discuss this with your teacher boss whatever if you have anything that you need to finish soon and try to find a way for them to accommodate you like getting some extra time or a decreased workload in the future also if you have anyone close that you are comfortable talking about this with then do so maybe they can help you out
