This comment of Vinisha, Mumbai, is interesting. So sharing with you:
"I don't really have a negative opinion on people who try to kill themselves. It's a personal choice really - they have their lives and they can choose to have enough of it when they please.
Of course, the vital question is whether people are really done living their lives. There's a sitcom on Star World "Grey's Anatomy" which had an episode on a 80 yr old guy who was in a coma for many years and finally woke up wishing he was dead. He tried everything from not eating to eating stuff his body couldn't take to sitting in a chair and using all the energy of his body into saying "I'll be dead now"
He doesn't die. He wants to because he's done living and everyone who was with him was gone with the exception of him. And then one fine day when hes ready to leave the hospital all dressed up, sitting in his bed by the window in the morning sunshine, he passes quietly away like a gentle breeze - sitting there just like that as if comtemplating back on his long lived life.
Sometimes I think I've had enough of living and then I decide to wait just for a little while more and see if I indeed have had enough and sure enough something else comes through that makes me want to live for a really really really long time. :)"
