Make sense? No. It isn’t going to.
However, you can adopt some ideas that make sense to you—take your pick; there are plenty out there, from Absurdism to Zen—and use them as a lens for viewing life. Then it will seem to make some sense, and that’s just as good, if not better.
As for the guy with the gun to his head, I would say what I’ve said before to someone who I knew was having suicidal thoughts: “I care about you. If you’re determined to kill yourself, I can’t stop you. I hope you don’t. If you want help, it’s available.”
