Has ever called the national suicide hotline and was it helpful?

I'm just curious. I've thought about calling a few tikes but never did. I heard stories of people calling and no one answered and I've also heard some people say that it wasn't very helpful. That was a while ago. It looks like they made a lot of changes recently. They're active on social media and it looks like they updated their website and added toll free numbers for bmobile, digicel and flow.
