Reverse psychology is not a good way to approach a suicidal poster. I know you meant your reply as a tough love/shock tactic, but what you have done is put the image of ways to commit suicide into the mind of someone who is already on the edge.

It’s better to get the person to talk about why they feel the way they do. They are then sometimes able to see solutions to their problems, or at least the possibility of a solution.
