I think societies had a simple curve for this. They help, help a bit more.. but after some time they drop the ball. Most average people have no clue anyway so they are powerless about the whole thing. People who know more may be able to go further in their efforts, but even then you're never sure you can carry someone like that for long. Even though .. I dearly think that most suicidal people only need a root deep emotional connection. Way too often people respond to shared pain, real empathy, understanding, trust ..
