As the mediator, I told the woman on the ledge she had nothing to live for.

I'm not an emotional support dog. I'm there to make sure they don't jump off the ledge and go splat on the concrete 25 stories below.
You need to use your position as a mediator to be more supportive. You shouldn't tell people things like that.
Hey, I'm fulfilling the requirements of the job description. If they want somebody to be all "Pretty please, don't jump," get the guy's mother to do it.
With all due respect, I think you're in the wrong field. You seriously need to reconsider your choice of profession. I think you'd be much better suited for a career as a Marine Corps Drill Sergeant.
