Take a step back Doemu. You want to satisfy a pulsion of death: does it make any difference to satisfy this pulsion in a well devised synthetic environment where everything is exactly framed as your ideal suicide scene: your ideal room with your ideal pills or your ideal rope, your ideal bridge, your favorite gun. Or a synthetic environment for drowning or for using gas or for cutting.
Technically we can expect that somewhere in the not so distant future, it will be possible to create a synthetic environment that cater to all suicide taste. You go there, and in ways that are currently worked on, your brain is directly corrected to a highly realistic android. A 100% accurate copy of you. As I said is your brain to control this Android, therefore, the moment your android prepare the pills and then drink them, you feel the process in you, at the highest degree, in a way that is more real than real. Same with the gun, is the android to use the gun, according to your indications (remember, the android is brainless, is your brain to control). And then you pull the trigger and kill yourself (kill the android).
I think we can all be critical to this way of "exiting", but if it would be available right here, right now, I would give it a try. After all the worst that could happen is that you will not die, like it happens in any failed attempt. But here you will at least have no permanent damage (your body is always untouched during the process, only the brain "perform" the process) and then you will be free to try again utilizing different methods, if you see this applicable to you.
