First, I would get drunk, to lower my inhibition. That would assure I would be more likely to go though with it.
Then, I would take my freshly-sharpened Dexter high-carbon chinese cleaver (It is sharpened to a 10 degree angle on a set of Japanese waterstones. The edge shines like a mirror. Scary sharp. I have a bald spot on my left calf to prove it.), press the tip right below my right ear, and with slow and steady pressure draw it across the underside of my throat until it reached my left ear. I would repeat until I passed out (probably within 5 seconds or so). Outside. It is raining outside, so the blood would wash away down the gutter. It is pretty difficult to f*ck that one up.
Otherwise, I'd hang myself. Just jump off of a bridge with a noose around my neck and a structural support. Like Bungie jumping but no *BOING*, just the snap of my neck. Granted, some poor schmuck would have to cut me down, but it would be similarly effective and would require a simple hop off the edge, not a sustained deep cut.
Not very glamorous, I admit. But when you just wish you could disapear, simply and quietly remove yourself from the realm of the living, why make a spectacle of your death?
A freind of a freind ****** up an O.D.. THAT sucks. Permanant braind damage and loss of personality for the rest of their days. Their family and freinds get to watch them walk around like a shell of the person they once were. They don't even have the wherewithall to finish the job.
Well, g'night all!
