Having worked in mental health for the past twenty six years and dealt with more cases than I care to recall, it is a selfish act. Escape your own problems and leave others to deal with them. I still meet family of those who took their own lives and still they ask themselves questions, could I have done more ? Why did they not talk to me ? One thing I did find though, all of those who did it, never gave us warning. Those who threaten it rarely do it.
