hard to think which year was the absolute worst for me. I think this is mostly because each year kinda balanced themselves over time so the bad kinda mixed in with the good, and as such every year kinda became the same to me.
honestly though, closest candidate would be 2016. Being completely unemployed for just about a whole year up until early 2017 and paying my hospital bills on top of that was not a fun experience in the slightest.
interestingly enough, best year would be 2017 for me, at least academically! ive made the best grades i have been for a while, i got invited into my college's honor society, and i've held a few jobs here and there. so overall, while 2017 wasn't amazing by any means, i can't say it was horrible. at least, not yet.
