what should I do I want to help this person but don't know how.

I’d go for consoling people, tell them that life is not as hard as it seems, try to empathize in some way by saying that you get it, it’s hard but nothing is worth that. That last bit may sound a little cutting to that person so try to just say “call the number they can help you.”
