I think the people who desperately want to die aren't too different from the people who desperately want to live. They are desperate for a life of some sort, perhaps a life through death.
They're certainly very attached to something.

However, when you're in the pit like this, you don't realize what's around the pit, and you can't imagine how you can live outside of it. I've been there, but I never seriously considered suicide because I know that my reality is far too mutable and insubstantial. My misery today will be my great joy tomorrow. If you can see the big picture, realize that when a night sky is above your head, there's daylight on the other side of the world, you can free yourself of this trap of fixed-perception.

You say your life is meaningless, so is mine. EVERYBODY'S IS, so what on earth do you gain by ending it? People who are suicidal are just trying to fix their problems in the only way they feel they can, BUT THEY'RE STILL TRYING TO FIX THEIR PROBLEMS. EVERYBODY IS.

People who live in fiction have the same problems as everybody else. They're real people, created in our image. We prefer to look at these fictional mirror lives than our own. At fiction's best, it offers us insight into our own lives. Your reality is someone else's fiction. But why do you wish to cut-short your fiction? You're depriving yourself of most of the series' episodes here!
