The Mental Health Foundation is the UK’s charity for everyone’s mental health. With prevention at the heart of what they do, they aim to find and address the sources of mental health problems.

For Mental Health Awareness Week (May 8-14 May), the key message was surviving or thriving. Exploring mental health from a new angle. Rather than ask why so many people are living with mental health problems, they will seek to uncover why too few of us are thriving with good mental health. This has been supported by the launch of a report:
Surviving or thriving: the state of the UK mental Health. (click to download) 
and see key findings and conclusions which include: Current levels of good mental health are disturbingly low. The barometer of success of any nation is the health and wellbeing of its people. We have a long way to go before we can say that we are a thriving nation. Although we have made great strides in the health of our bodies and our life expectancy, we now need to achieve the same for the good health of our minds.

They also have a range of publications and resources related to managing your mental health such as in the workplace, improving your sleep and managing stress. See website for further details.
