[header] How to talk someone out of suicide [title] Contact emergency services immediately if someone is about to commit suicide. [step] You need emergency responders, especially first-aid, to be there as soon as humanly possible. If you need to be with someone and they won't let you call, try to get someone else to call. 
If someone is on a bridge, holding a weapon, or otherwise threatening their own life, your first move needs to be to 911. You should never try and handle this on your own.
