having a slump in junior year

idk why, but ever since October, I've been feeling really weird and unmotivated. I usually get good grades, but this quarter I've been getting lower grades than I usually do 😭 I also missed a week of school due to being sick and now I'm just overwhelmed with all the work I have to do. when a situation like that happens, I pull through and quickly get everything done since I don't like procrastinating, though this time i just feel stuck and i don't want to do anything 😭😭 does anyone have any tips on how to get over this quickly?? ngl this isnt even just for myself, but as no.1 people pleaser i dont want to disappoint my teachers, nor ever experience a teacher pulling me aside and giving me the 'is something going on at home?' talk 🫩 helppp
