Having worked with lots of suicidal people over the years and having lost my first husband to suicide, I just want to say that some people have too much pain to live with, very often through terrible circumstances and no fault of their own, but they still are the ones that have to live with it. It's no-ones place to convince them to live with that pain longer than they want but having someone just be there, listen, and care in the end is an amazing gift to give, even if i's the last one they can receive.
