I know I might cause an argument or something, but I felt the need to post this.
My cousin was suicidal a few years back because his father was being very uncaring and abusive. I visited him at a mental institute and brought him a Bible. a few days later, he was up and doing things again. I believe that it gave him the words of encouragement to continue living.
You can ignore my advice, I don't care. That's at least how we saved my cousin.
