Personally I believe that life IS hell, and anybody who has been evaluated for mental disorders (other than suicidal tendencies), and found that nothing correctable is causing their feeling that life is not worth living, and has spent many months of suffering to contemplate if its true should have the RIGHT to end their suffering.

Of course,
if I knew that I only had X many days left to live, hoho, you don't even wanna know what I'd do!!! (but I'll tell you anyways)
First I'd call up my boss and tell him to fuck himself ("nothing personal I just never want to work again"), then burn all my schoolbooks, spend every one of the X days on various doses of MDMA/Oxycodone/Fentanyl and occasionally Methamphetamine, LSD or 2CB for flavor, marry my chick, try to fuck every beautiful woman (hell, men too if I found one I'm attracted to - unfortunately I never have!) I've ever met (and hopefully a couple would be kind enough to oblige), I'd get somebody to adopt my kitties and lick them goodbye (odds are my chick wouldn't let me kill myself alone, its both or nothing, so this story assumes she is already gone or is coming with me!) I'd look into some "Vigilante justice" against the drug war, take out a LARGE life insurance policy, and on the last day donate all of my money to every charity listed on my site, call everbody I know and tell them I love them, rent a sports car and find some winding mountain roads to do some time trials on (I'd compare my times before and after candyflipping). Then I'd climb to the top of some obscure mountain (nature will take care of the mess!) with 50mg of cocaine HCL, a couple grams of heroin (no tolerance) and a needle (I don't do needles, but why not!?), and maybe a 1L whip-it dispenser and finish the job! (I'd probably have some promethazine so I don't puke)
The alternative situation, where I find out I'm going to die in a hospital, involves me pleading the nurses/physicians for as much hydromorphone and fentanyl as they are willing to part with.
*DROOL*, unfortunately my psyche won't let me do such a thing, because I know that I'm healthy and I exist for a reason. I think that reason is to advance the world in computer science, and fight against injustices big and small against all people, to keep various druggies safe and away from harm, and to keep my friends happy and give everybody love.
