Your doctor needs patients. You need a doctor. Without one another, then the world would be meaningless. What’s the point of killing yourself, anyway? You’ve probably got shit to do tomorrow; at least finish the shit you gotta do, even depressed people know they are leaving stuff undone. Life isn’t meaningless when you interact with the world. Non-interaction is a lack of getting stuff done. You will be depressed and find life meaningless if you do not interact with the world. The purpose of life, whether you think it’s bullshit or not, is to literally be in the world, to exist. Something insisted on you existing, otherwise you wouldn’t exist. So don’t let that insistence go to waste, interact with the world, do literally anything that needs to be done, and then find life meaningless.
