I've often thought about forging a DNR order, complete with faking a signature of a real doctor, so by the time they can figure out it's a fake, I'd be dead. However, I imagine the consequences of doing this are dire, on the chance that I am resuscitated anyway. Truly wonderful to exist and have no ownership and authority over your own body and personhood. Not only this, but they'll lock you in a mental hospital immediately after.
People often wonder, 'how can someone have the courage to go through with hanging themselves." It's not courage, it's complete abandon in the face of the systematic cruelty we're faced with in the world. There was a thread here about whether or not the future will have better and more peaceful ways to end our life: No, it will get worse. We already have a substance that will let us end our pain peacefully, and we are forced into the most obscene and undignifying circumstances just to keep that substance, and similarly peaceful means, away from us.
