Funny, I had a colleague who we all thought had cancer (terminal), fundraising had begun for treatmenet etc. Anyway another friend and I went over to see him one evening to play computer games and just hang out, as he seemed pretty down. During that time we were chatting about his cancer etc. and the subject of suicide came up. I (apparently) said that "I thought it was the cowards way out" (I do not feel that way any more I may say)
Anyway, apparently this stuck in his mind as he had been planning on committing suicide that evening. He never told me this, but it was relayed. Turned out the cancer was entirely made up as he wanted to have a legitimate excuse for committing suicide!
He’s well now thankfully.
It’s funny the tiny chancy things you can do that can have huge consequences.
My heart goes out to this family, and if you do have friends / colleagues that are down or talking darkly. Do reach out to them (however uncomfortable you may find the process), you might really make a difference.
