When half of us, on average, will experience a mental health problem in our lifetime, and one in four New Zealanders are currently, it's a reasonable question. By now, shouldn't we all be aware of what mental illness looks like?
Dealing with mental health is a constant battle against the tidal wave of denial. The history of psychotherapy is a century-long effort to demystify and promote the treatment of mental distress because, for many, their personal battle is one against their own - and societies - denial.
All mental health problems share a common cause: the experience of one's emotions or thoughts being out of control. And at its simplest, denial is fuelled by fear. It's very human to be terrified of losing control of our thoughts and feelings.
The other response to fear is to attempt to control that which frightens us. Some of the worst atrocities, cloaked as treatment, come from an attempt to isolate and control those who are suffering. Asylums, institutions, historically surgeries like lobotomies and more recently the use of chemical restraint (sedating people to keep them quiet) are very real examples.
Stigma and discrimination is the more subtle version. When we fear something, and deny we will ever suffer it, we shun those that do, and attack them for that which ails them. We put them down, push them away, and make them "not us" in an attempt to control our own fear.
