Few years ago I tried to end it all but fortunately I failed. Now, years later, I see those same signs in people around me, my friends, colleagues etc. I wanna help them but I don't know how to. I know the obvious answer is to talk to them but I wanna know if there is a correct way I can learn.

P.S. I am incredibly shy person which makes it hard for me to approach people with sensitive topics and my outlook on life is generally not accepted by people so generally I don't know what to say.
