Things that work for depression: writing, composing music, exercise, playing video games. Things that don't help: alcohol nor drugs. Role of family and community: YMMV. I envy lots of folks with supportive and kind families, but I also witnessed much suffering and terrible loss caused by a loving family that doesn't quite get the loving part right.

With that out of the way, I'll say that for as long as suicide mortality is well below cancer mortality, society doesn't really have a suicide problem.
