How to kill myself in a way that is painless?

Thats so fucking gay.

What the fuck are you even talking about. One quantum physics IS real. Its used in designing yoir phones and compiters and two there is absolutely nothing about it that supports the existence of an afterlife. A few idiots have blatantly misinterpreted it to support the existence of free will, but I can even imagine how poor your understanding must be to think it is some how related to the afterlife. If you want a theory to mis interpret and generally make shit up then string theory is what you want. Jesus.

Don't do this one. We are running out of helium on earth. Plz use a different gas ir method and leave the helium for those of use still stuck here.

In the country I live (not born here) is pretty common to people to kill others or kill themselves by blocking all the windows and dors and turning the gas on. It's slow put painless, and you pass out quickly

A Redbull, a gas station coffee, and a large soda of your choice.

Stop drinking water & eat only the smallest amount of food for a week

Why not let a fellow user enjoy your death? You could arrange to meet, ensure you've left no traces, dig a shallow grave, and let them shoot you in the head. It'd be fun and painless.

You should have an epic death.
