I have an illness that isn't considered terminal as such,but it is incurable and I will die because of it.I will very likely be in a great deal of pain and unable to breath unaided.That is not how I want to spend my last weeks or months on earth.I would much rather be able to say to a doctor "right,i've had enough,please put me out of my pain and misery".There is every chance I will be unable to actually take my own life and will need help to do so,I would not ask my family to help because I wouldn't want them to be prosecuted for it.
