Reaching out and helping people, it's something anyone can do, I have done this multiple times. It can be harrowing to hear that your friend was contemplating suicide, but it's better that they dont.
its only happened on twitter once, but I never knew the person, again, there were signs of potential self-harm that needed to be addressed.
(Social Media has made this a lot easier)
My Inbox is always open and I will never ignore you.

It was one of these which made me realise that not everyone who is contacting you might have issues with depression.)
