I once heard this :
If there is at least one person who will cry at your funeral, then it is not worth dying.
Then I have to add this as well : We all have a death wish, but we all think suicide is extreme. When our moods take a swing, we think of death first and foremost. But consider this - Understanding the implication that death itself is almost no longer mysterious or frightening to us should make you hold on to what remaining life you have more tightly.
Excerpts from The Last Samurai
"You do not fear death...but sometimes you wish for it?"
"...To taste life in every breath, every cup of tea, every life we take...That - is Bushido."
In a sense, we are all olden age Samurai, feeling out of place in this modern world which no longer requires those who do not fear death, but have a loyalty to those whom we seek to protect.
So live for those who love you, and for those whom you love.
Plus, I sincerely hope you don't try anything funny after this, or I might just feel bad about it and get hit into another DP trance.
