Concealment culture?

I've just read this NewScientist article about the existing 'taboo' that surrounds suffering from a mental illness and revealing it to others with confidence.
Despite a wave of celebrities openly admitting and embracing their mental health problems it would seem the majority of normal every day people still fear the stigma of being 'crazy' or incompetent, and so hide their diagnosis from family, friends and colleagues. This instantly saddened me, but what affected me more was reading that almost 80% of people with depression experienced discrimination because of their condition in 2010 alone, and that a quarter of sufferers have been rejected from job positions because of their mental health.
Erm, are you freaking kidding me?? Firstly, I would just like to say that, really, if your work environment is one that couldn't possibly be accepting of any mental health that wasn't 'perfect' (and there is no such thing, don't kid yourself) then quite frankly I wouldn't want to work for you. But I can't say I'll always be able to be as picky, what if times are tough and I need that job? If you discriminated against me because of my gender, race, age, sexuality then that's a big no no, mental health is kind of....meh. Unfortunately people still seem to feel that if you're depressed/schizophrenic/anxiety-ridden/obsessive compulsive then you'll be of no use to their workplace and a drain on sickpay etc etc. I am just as competent as the next person you pluck off the street, and it riles me that one day I may feel like disclosing my mental health history on a job application isn't in my best interests.
There are two quotes I remind myself of when I'm feeling particularly aggrieved at the naff hand I was dealt by the Gods of brains. One is something my lovely GP said to me, and the other is from Bill Clinton, from whom I don't ordinarily take life guidance.

'Depression, and any mental illness really, is only a flaw in the chemical make-up of your brain, not a flaw in your character.'
'Mental illness is nothing to be ashamed of, but stigma and bias shame us all' - Bill Clinton

The piece cites Ruby Wax, who is famously outspoken about her own experiences with depression and one of my girl-crushes. She's funny, she's human, and in an amazing TEDtalk she gave last year (which you should definitely make time to watch) she said something that completely rang true with me:

I guess what got to me most was reading about the cyclical nature of mental illness. Society still has a bit of an issue accepting and understanding ill-mental health, so those who are given a diagnosis don't reveal it to others, don't want to embark on any new relationships and because of this feel more alone and excluded and more unable to reveal their condition. Equally, everyday man-on-the-street doesn't challenge his perception of 'normal' or of 'depressed' because he doesn't realise that actually his own son has depression, and so did the girlfriend he had in uni and Joe from HR at work and his great-aunt Margaret. Work places don't want depressed people in their work place, so none of their existing employees feel they can disclose they've been having a hard time recently, no potential new colleagues apply disclosing a mental health issue and the work environment remains an unhealthy one.

Time to Change and other movements like it within the UK and across the world are undoubtedly helping to change the idea of what it is to be normal and what it is to be afflicted with a mental health condition. Whilst I feel confident that the stigma is reducing and changing, I'm worried that it will never disappear entirely, and that as I grow older I'll be faced with the dilemma of choosing whether to openly reveal my history at the risk of being shunned or discriminated against or stay quiet and feel like I have to face everything shamefully alone.
Of course with the rise in employers using the internet to research potential candidates there's every chance someone is reading this right now. In which case: hi there, please give me the job!
