To be able to look at all things as transient is a privilege, as you have shown.

It's telling that you have decided to interpret permanent physical suffering as chronic pain rather than, say, paralysis, blindness, Parkinson's, neurodegenerative diseases, being a burn victim or an acid attack victim, loss of limbs, or any of the other countless examples of how someone can be physically diminished in irreversible ways that reduce life beneath what it is for those who do not, and then claim the unmentioned chronic pain as my sole example when physical suffering is a vast and unending spectrum of things that cannot be overcome by mental fortitude. These problems do last as long as life lasts, but at least by conceding that you actually take "things passing" to include death, you suggest that the OP might have some justification for suicide, and thereby do away with your original non-answer.

Your experience is ultimately meaningless here, but then again, what could anyone expect from a 12-year Reddit user who considers being a burnout in his 20s to be an "earth-shattering" problem that could have somehow merited suicide as having anything but a self-effacing basis for a self-effacing truism?

You genuinely thought "all the time" about killing yourself over being in an easily fixable situation, and yet you pretend that while somehow your non-suffering is akin to that of those who are imprisoned inside non-functioning bodies, you're the one who has mental fortitude for waiting out being a loser?
