This is not serious, useful advice like the other posters (and pls listen to them)... but I always thought, if you are considering suicide, why not fake your death? All the good stuff like re-birth, freedom, and what not... without the bad stuff.. like being dead forever.
Well, if you have life insurance that constitutes insurance fraud. If you have people that care about you (and its probably safe to say virtually everyone does), you have just done a lot of harm to them. If you have responsibilities, this probably means you are abandoning them.
If you succeeded in faking your death (very hard to do in modern society, I would suspect) you may gain some benefit from it, but you will cause problems for a lot of other people. Not to mention the problems you bring on yourself if you are caught could be very substantial.
(I thought it was a funny post though, even if attached to a serious topic. In all seriousness, if you are having suicidal thoughts, seek help.)
Some people do this virtually. They delete their facebooks or myspace pages, and go invisible so nobody can contact them except through email , phone, or meet in person. I'm afraid that in the short term, finding out how many people care about you is great, but if you regularly seek attention in such a serious matter, its like the boy that crys wolf, people will grow tired. Be Careful.
