The way that "This is Water" speech/pamphlet is brought up in particular horrifies me. Hindsight granted, it's always read to me as someone who, stuck in a deep, dark hole for so long, has given up on finding a way out. Blaming himself for being there in the first place. Standing so close to an answer, but unable to see it. And we know how the story ends.
It's a feeling I know well, and I'm routinely shocked how people without (I assume) first-hand experience with depression can completely ignore the darkness there, and see something banal or even encouraging.
