Chester has never been great at articulating his feelings in a "mature"/complex (whatever that means) manner. He certainly manage to do so once in a while, but these lyrics feel much more natural based on how he speaks normally. I honestly feel this song is very personal - to him at least - and, thus, feels very much like him just having a casual conversation about his depressed state in 2015/2016. Some of you assume these lyrics are just pandering to a certain demographic but based on the aforementioned I feel like there is more to it than that. I feel like Chester is singing from a very real place. Whether or not that is cringy/angsty to you is your provocative.
