Last month, the Prime Minister David Cameron delivered a rousing speech pledging almost a billion pounds in an attempt to address the mental health crisis which has gripped the UK.

And make no mistake, a crisis it is. The four most common mental health issues in under 21s (anxiety, depression, self-harm and eating disorders) have, according to some experts, collectively risen by 600pc in Britain over the past decade, hospitalisations for self-harm and eating disorders have doubled in the past three years and unexpected deaths arising from mental health conditions have soared by 20pc over the same period.

So it was perhaps fitting that David Cameron made specific mention of teenagers with eating disorders (the government has promised to reduce NHS waiting lists for treatment for anorexia) and to mental health services in A&E departments. He also outlined plans to ring fence £290 million for mothers suffering from postpartum depression and psychosis, conditions which have been largely misunderstood and certainly underfunded heretofore.
