I go from thinking this is a terrible method to thinking it's one of the easiest.
Bros I don't understand all this stigma and speculation surrounding "methods". Maybe it's a positive and maybe it's a negative, but since highschool I've known the most painless method and exactly why it is so effective and popular: hanging. Most people think it's this hugely painful choking out before finally losing consciousness, but it's so very not anything like that.
Do you know about the "choke points" that wrestlers use all the time? It's easy to find them. Just take your fingers, and look around your neck for a couple of noticeably huge veins, the same veins that you check to see if someone's dead. There is one on each side of your neck. Mine are parallel, each around the back and directly below the back of my chin. It's easy to find them.
Now that they are found, try this thing:
Stand up straight with your back against a wall, with nothing you could whang your head against while you lose consciousness for a bit. Now bend down, the further the better, hopefully with your head below your waist line at least. In that position, take, oh, say, 20 deep, rapid breaths, emphasis on rapidity more then depth. Next, immediately stand up straight and use the side of your palms, the side closest to your pinkie fingers, and push them against the veins you found earlier. You'll start to see your vision swim, and blackness will encroach from the periphery of your vision, swimming inwards. Just keep holding for another second or two and then you'll wake up on the floor and you'll feel your brain starting to reboot.
The only extra step, the only thing different from you and a professional wrestler, is suicidality and a rope, or a belt, or I mean honestly the list goes on and on; where there's a will there is a way, and all of that.
Bam, you find yourself on the ground with no recollection of how you got there, and you have a newfound peace, knowing that in all but the most severe of imprisonments, you can ctb with no pain and no awareness of dying.
I do not understand how this is not more commonly known. My opinion is that among the right crowd, the people who are not making a statement or dramatizing basic depression, this is known. It has to be. All of my heroes hang themselves, so this isn't some big secret, but why is it never mentioned?
