I... am not sure that that's good enough to take "My life is unbearable to me" and respond with "well, you just have to bear it, because no-one's going to help you die." To me that sounds almost as bad as the "suicide is wrong because it's selfish" thing one hears so often, as though wanting people to go through the pain of recovery from whatever makes them suicidal (assuming such recovery is even possible) is somehow less selfish.
