You're being downvoted, but if you read advice on how to help people currently experiencing suicidal impulses, one of the first things you learn is not to try to combat them with messages of guilt or obligation.

As I understand it (surely someone on HN has more exposure to this than I do; I've lost friends, but not myself experienced the impulse):

The "do's": listen, empathize, stay calm, be hopeful in tone, vector them towards help.

The "don'ts": argue them out of it, get emotional, judge, try to fix it yourself.
