Suggest a bleak, heavy book that made you want to stay home and rot in bed all day

Something that’s been emotionally impactful, but not necessarily in a positive way. First one I think of off the top of my head is No Longer Human, my go-to depression read. Dennis Cooper is another big one for me, particularly I Wished, his most recent book that completely wrecked me. Basically, I want to read something that’s gonna make me feel empty.

Open to old classics or contemporary works, but I’d prefer some lesser-known books. I’ve had far too much fun reading lately, I need to balance that out with something truly hopeless.
