A suggestion - if ever someone says to you that they just want to die, to end it all, talk to them. Listen to them. Nobody really wants to die, they just want whatever-it-is that is hurting them, to stop hurting.
I ask a question - if you had a magic wand that could grant you three wishes, what would you wish for?
The message here has to be - if the magic wand can grant wishes, it can do magic. it can change the world. You could even have world peace if you want. You can change ANYTHING. So what do you want?
The answers will lead the way. They can be very different, they may not be what you expect, the person giving you the answers may also be surprised at what comes out.
The next step is to try and grant the wishes in some way, somehow.
A woman I spoke to said she didn't want to be alone any more. So we organised for her to go stay with her brother while she re-thought her life. it goes without saying that she also took herself off to counselling, because in asking her three wishes, she realised she didn't want to die, she just wanted her emotional pain to stop. That was wish no 1. And a therapist, plus living with her brother, made it easier for her to keep living.
A child can do this too. Children don't always understand the finality of suicide, for them it really is a desperate cry for the pain to stop.
