I understand your need to put some emotion into what you're typing, but please try avoid putting fucking fuck in every sentence, it makes people not want to read it, and you won't get many responses, if that's what you are looking for..
Back to the topic - If this person is serious about wanting to commit suicide, and you have a feeling that they would actually go and do something like this, and they're not just crying wolf - Then I would immediately let someone who can help them know ( police/family/dr - anyone who could genuinely help ). If anything you are saying to them is not helping the situation, then find someone who can help.
