I think if someone announces that they're going to end things to all and sundry, it's a cry for help. Those who just go ahead and do it, mean the business. A lot of youngsters, fuelled by depression, pressures, lonliness or whatever, really just need understanding and love. Of course, mental illness can also drain a person of being able to see their way forward, so in their desperation, they want to opt out of life. I think any threat should be taken seriously though, as even if the person wouldn't actually do the deed, they're feeling miserable enough to contemplate it.
