I think there is more to this topic than just "Not taking your life."
In my opinion, it is about taking life into your own hands, owning it. There have been times in my life where I was better off than I am now yet did nothing with it. I was just sitting/lying around, wasting my life away. That is a form of suicide as well, the slowest and most wasteful kind in my book. And a lot of people go through that as well.
Depression is a tough topic, but it is a topic that one should own, not be owned by. The life belongs to the human, not the depression.
RE: Remember, your life is valuable. Do not take it or even think about taking it!
