Mental health is how we think, feel and act as we cope with life. It also helps determine how we handle stress, relate to others and make choices. Like physical health, mental health is important at every stage of life, from childhood and adolescence through adulthood.
Mental illnesses are common - they affect about one in five families in the U.S. These disorders - depression, phobias, bipolar disorder, schizophrenia and many others - are real diseases that you cannot will or wish away. Fortunately, they are often treatable. Medicines and therapy can improve the lives of most people with mental illnesses.
