Depression and unhappiness are the main reasons for wanting to comittt suicide. Possibly the only reason.
?
give them a reason to live. that may be harder than it sounds, because that reason can be different for everybody.
but if you can give them something more than just tangible things, and, more than anything, let THEM feel like they have a choice, then things may start to feel more amicable.
just don't treat them like a "patient", but like a fellow human being...that is modern methods' biggest flaw.
