is there any situation where you could be overcome with grief and end your own life?

I think the only thing that could bring me to the point of suicide would be the death of my children, certainly if I was the cause that would be even worse. If only one passed away I might manage to pull through for the sake of the surviving child but it would be hard for sure. If both died I don’t think I could go on, I wouldn’t want to go on.

The entire world is burned to a cinder while I’m standing on the moon all alone watching?
