Long-term disturbances of mood like depression and bipolar disorder are considered mood disorders. The document provides suggestions for overcoming mood disorders, such as breaking large tasks into smaller chunks, not comparing oneself to others, engaging in concentrating activities, exercising, being assertive, focusing on the present moment, and watching funny movies.
