I've said much the same thing before:
I have an untreatable, incurable cancer. Fortunately, it's slow growing, so right now I am getting along just fine. But eventually it will lead to an ugly death, most likely either from liver failure or right sided heart failure (basically drowning). Quality of life is, to me, far more important than quantitiy. When I reach a point where I am merely existing, not living, I will have a party, tell my loved ones thanks for everything, go to bed, and I don't really care if it's legal, for me, because I have the knowledge and resources to make it possible regardless. But for others, yes, I wish it were legal.
I see patients every day who are dying miserable deaths. For those who want life prolonged at any cost, I do my best. For those who just want to be allowed to die with a little dignity, I also do my best, within the limits of the law. But I wish we could grant the wishes of both.
