There are many searches for how to kill yourself on google because lots of people want to kill themselves
First we would like to say that life is worth living and you should not kill yourself.
But if you really want to die, the easiest way is to hire a hitman on yourself, they will come, kill you and go away.
If you are lucky they don't come and you just wait. No, I am kidding, they will come and they will shoot you with a silencer and you die painlessly.
