One of the things that annoys me is the people that often put themselves forward for the position of "Mental Health First Aider". My last company did this and they had 3 of them. One guy did it for genuine, altruistic reasons. The other two were the office gossip and the corporate arse-kisser who was the biggest bully in the company - the last two people you'd ever open up to about a personal problem.
If the company aren't serious about the issue, if they just treat it as a tick box exercise, they can make things worse for people.
