On Monday, the Prime Minister is expected to make a major speech on mental health, in which she will promise to provide more training for educators and employers.
But the lights on the dashboard have been flashing for some time.
We now live in a society where one in four people will experience a diagnosable condition during their lifetime. These can range from common conditions such as depression and anxiety to more severe and enduring conditions such as schizophrenia.
Mental health problems among young people are at record highs, with self-harm among under-18s increasing by more than 50 per cent between 2010 and 2015. In 2015, there were over 6,000 deaths recorded as suicides, marginally below the 2013 level, which saw the highest rates since 2001. Presenteeism caused by mental health problems – when people continue to turn up to work despite being ill - costs the UK economy £15bn a year in lost productivity.
How have we got here?
NHS mental health services have always been chronically underfunded compared to those designed to improve physical health. Mental health accounts for 23 per cent of NHS activity, but receives funding equivalent to just half that proportion. While hugely important, underfunding alone cannot account for the current crisis.
Another factor is the rapid pace of change that characterises modern society. Globalisation has changed what it means to be happy and healthy, either at work, school or home. Both government and society have, though, failed to keep pace with this rapid change.
As a result, schools find themselves on the frontline of supporting young people as more of their lives are played out online - 81 per cent of head teachers reported an increase in the number of pupils affected by cyberbullying in 2016.
Employers have often failed to protect employees overburdened by stress, which now accounts for one third of all work-related illness. And the government has failed to protect those who are suffocated by low-pay, poor housing and an uncertain future. Its Work Capability Assessment has been linked to increases in suicide and mental health problems among participants
So where do we go from here?
