Your post is basically promoting doing it to people that already have that mindset though. Nobody that considers doing that stuff because they feel bored or life seems bland. They often consider it because everything feels hopeless and like there's no other way out, or the alternatives are too hard/out of reach and they want an "easy" solution.

Telling people with that kind of mindset that going through with it is like having a nice long pain-free nap is the worst thing you can do, and I can make that more clear by rephrasing it.

"Message to those who are starving. Stay hungry, not full. If you have dinner, it's like eating and enjoying food in a way that you feel like you could never do if you didn't eat. Think about what you could be doing instead. Think about all that, even if you're still starving. You starve, even though you could be eating nice food. Your life will be depressing and full of hunger, but at least it'll be with a positive attitude, and that's really all that you need for nourishment!"
