As an idea, we could possibly discuss our experiences with getting help for the first time? I know that for me at least, it was the hardest step. Since it is quite daunting, people may be more inclined to reach out for support if they know what to expect.
I'll also try and get involved as much as possible this week - it's obviously very important to eliminate the stigma. On the bright side, I have noticed that mental health has been discussed very frequently in the media over the last few weeks which is great!
