I took from it that the suicidal person's time horizon got shorter and shorter until a moment before dying they're focussed on the most minute of details (literally crumbs) and unable to look further ahead.
There may also have been a sort of parallel between stomach pains and mental/emotional pain.
What do you expect to understand? This is a morbid story written by someone who committed suicide. Or are you talking about a higher meaning of the writing?
I feel like I understood it, but it is hard to put into words. I find that strange.
Emotionally it is easier to explain: It makes me feel like I did after the first time I watched American Beauty, read The Yellow Wallpaper, or listened to Bush's Razorblade Suitcase start to finish. Surreal maybe.
Perhaps in this case understanding is more emotion than cognition?
It is a slightly embellished (but based on his real life) narrative of him coming back from a vacation in Europe, dealing with some sort of stomach flu for about a week, getting fired from Reddit, and getting all emo about it.
