Having a mate in your corner can make all the difference when you have a mental health problem. So, if your mate is acting differently, step in. It's not hard - read these stories to see how it's done.

It’s so important to surround yourself with loved ones who care about you and acknowledge your mental health difficulties. You need a stable support network around you, even if it is just one or two people you can really count on.
