I keep being in the same situation lately (not the pickle juice tho sry). My school gives us tons of work :/ I’m currently doing 3 subjects and they all give me about 8 hours of work per week outside of lessons. I’m also doing this other thing which is like an extra 2-4 hours (it makes me want to cry fr).
I think it’s just best to stay motivated and focus on your goals. If you think too much about the workload, how your don’t really want to do it or whatever then you’re just going to be distracted or want to procrastinate. Stay focused on your goals and remain positive! Also remember to take breaks and get plenty of sleep even if it means not being able to finish some work
