Life isn't always happy bunnies. I can tell you right now I'm in a pretty s****y mood, but you persevere. The fact that dad pulled through shows that it would have been futile topping himself. Read the book of Dave and it's pretty obvious that Will Self hit rock bottom and was suicidal at some point. But if he'd done it, given in to the idea of the futility of life, we wouldn't have had his quality contribution to Shooting Stars. Genuine medical reasons aren't clear cut, particularly mental illness, severe depression and chronic (terminal) pain. I just say there but for the grace of god* go I, but to say "One could argue that it's selfish to expect someone to carry on their unhappy life just so you don't have to be sad" sounds a little flippant, especially if they come out the other side stronger for the experience. All just my opinion obviously, I'm no expert in ethics, psychology or religion. *or flying spaghetti monster
