To refine my earlier post after these six pages.
Suicide is rational when you're merely choosing your method of death over choosing to die significantly before you'd otherwise die; or when the remainder of your life would be filled with pain and suffering.
And suicide is rational when it's a sacrifice for the good of others.
But I've seen idiots that are truly deeply offending in their stupidity; I feel myself disgraced for just sharing a species with them.
Suicide is the greatest expression of your own freedom there is. It is truly the greatest, most important decision a person can do. To claim a right to decide for someone else if they are allowed or not is incredibly arrogant, to the point I doubt you can understand anything about people, as blinded by your own hubris as you are.
And to those who say it's a coward's way out; a weakling's way; a selfish decision; that there's things they could easily do to improve their situation...
Well, first of all you're idiots of incalculable caliber and somewhat explain George Walker Bush if you're frequently appearing enough.
And secondly, a death is almost never a life-ending process. (For other people than the one dying, obviously.) A person can truly be a burden to those around them; and as painful as the suicide of someone close to you can be, their continued living could well be worse, no matter what you would feel like when confronted with the situation.
Suicide isn't always selfish act.
Choosing your fights is important. Some fights you just cannot win. Continuing to fight on is not always the best decision; for you or others. Sometimes, all that awaits you is loss and pain.
Suicide isn't always a cowardly act.
No amount of strength can overcome some obstacles. The failing of one's body will turn even the strongest heart unable to overcome what life throws at them. If life gives you lemons, make lemonade. If life gives you shit, suddenly the analogy doesn't work.
Suicide will end all problems. It's a part of it's beauty - the most essential part of it's beauty.
Suicide is never a sign of weakness.
And to improving your life... this, here, is where the colossal idiocy starts. I already said that people in the other points made George Walker Bush perfectly understandable. This point takes that stupidity, then scales it in a way beyond any terms. Think of a supermassive black hole compared to a quark; a difference in magnitude too large for humans to meaningfully comprehend.
When a person is suicidal all of those strategies fail instantly. Army and similar options result in loss of freedom; a thought for many more significantly more scary than death.
Getting a job and such in general are impossible for someone depressed enough to be suicidal; depression causes significant side effects that will get them fired.
They could live on the streets and try to bum it out, but that is more like the thing causing people to go suicidal rather than helping them.
And to top it off money rarely helps depression, because depression is a fair bit deeper than just being broke. Depression is a fair bit deeper than not getting laid. Depression is a fair bit deeper than any of these ordinary day worries. And getting friends / a significant other - while often helpful - can also easily prove impossible for these people.
So, to summarize this last point: If you say something like that and mean it... what the hell has to be wrong with you?
