This is quite a tricky one
On one hand, removing the stigma and undoing the fatalism associated with depression is absolutely necessary, not just to ensure that everyone who needs it gets timely and appropriate help, but also because more balanced attitudes help sufferers live better balanced lives, which in turn aids recovery. So "coming out" about depression may be a positive step.
On the other hand, the prevalent attitude towards depression and other forms of mental illness is still characterised by suspicion, avoidance and mockery, which makes sufferers understandably wary of putting their hands up to identify themselves.
It'll be interesting, therefore to see how this poll goes, but I think it's likely that many will have reservations about trusting its anonymity.
For my part, I had a bad back for years, until it went completely and I couldn't walk. Then I saw an osteopath who sorted it out. Now I pop back every few years for a tune-up.
I also had undiagnosed depression for years, and it took a crisis to get me to look for proper help. This wasn't as neat or quick as osteopathy, but it's made a similar difference, and as with the back, I only wish I'd done it sooner.
As a certificate holder, I was initially worried that a diagnosis of depression could mean the end of my principal form of exercise and recreation, but fortunately both my GP and FEO took the view that my hobby was as therapeutic as my treatment, and time has proved them right, I think.
Indeed, it's hard to think of anything more counter-productive than taking the opposite view and causing individuals to avoid treatment for fear of losing one of the few pastimes that makes them feel they're still in touch with the truest part of their nature.
And no, I haven't voted.
