Can you tell me how many methods that i can use to kill myself soft and not painful?

Change a mood, and live for the future

要不你吃几百粒安眠药吧 - -

you can keep yourself old but health and happy enough to die, that's the safest and softest way.

Lie a track
Jump off a building
Sleeping pills

die like son goku did-fight till death. then use the dragonballs to return.=p

Tomorrow will be better!
