It's an easy path to fall down. I went from taking no days off in three years and working every holiday to taking three weeks off in a year because I "wasn't feeling well" (depressed). This is way too relatable.
In my 3 years at my current school I never took a day off. Never got sick. Now I skip a lot of mondays and Thursdays because I just fucking can't cope with those days. The Math and IT classes are too much and I just run away. I dread thinking of these days.
My teacher and classmates even noticed how someone like me suddenly has "headaches" or "stomachaches" every now and then. My future is fucked.
