Not always true about the statement Someone who is determined to die, will not be telling the world his intention.
One of the guys in the same camp told us he can't take it anymore when we were eating at the cookhouse, he was quietly crying, his tears were going into the food. The thing was, he had said it so many times that no one took notice. It was that same evening that he jumped.
I heard some of the guys in the same camp who was also contemplating suicide were saved by the counsellors subsequently. They were saved because finally someone took notice.
