I suppose I have, but it almost didn't work.

Met him online in a little support group type thing. Got to talking, really nice guy, but he just could not get it through his head that life was worth living. He had a decent family life, no job and not many friends at all but things definitely could have been worse. But he had horrible depression and I personally understand that no matter how great your life technically is, it doesn't matter. We were talking for a couple of months at this point. I didn't know what to do to help him and get him out of his current mindset. I let him vent as much as he wanted at any time of day I could offer, looked up recreational activities he could take up in his hometown, tried to give him ideas of things he can do to take up some time. He said I was his only friend and listened to everything I said but never took my advice. He would tell me every day that this is just not working. I basically begged him at one point to just take a breather, take a walk, go out somewhere public and social. Anything besides sit in his room day in and day out and be alone with his thoughts.

He stopped contacting me for about a week. I got nervous. Then one morning before I woke up, I got a message from him along the lines of "Thank you for your help all this time. I really do appreciate everything you've done but I just can't be helped. Watch the news for my town and keep a lookout for [certain train station], I'll be on there in a few hours."

I panicked and looked up news articles for his hometown. Sure enough, a man was struck and dragged under a train as it was pulling into the station.

Thankfully, since the train was moving slowly, he was not killed. He was severely injured, being trapped for a long time under it until they could pull the train off of the tracks to retrieve him. Ended up losing his arm at the shoulder and screwing up his leg pretty badly, but he was alive. Witnesses claimed he was walking a bit too close, fell under it right as it was passing by, but immediately screamed for help when the train caught him. I was glad they did not mention/know it was an attempted suicide but upset that I knew the real reason behind the article.

We still talk to this day, though not nearly as often. He has a decent job, is getting a newer, fancier prosthetic arm soon, more friends, still battling depression but no longer wants to end his life.
