Mood Disorders

Mood Disorders can cause someone to feel sad all the time, to lose interest in important parts of their life, or may cause extreme happiness or sadness.

Mood disorders are treatable medical conditions. With an appropriate diagnosis, treatment, and a support system, most people struggling with a mood disorder can be treated.

The most common mood disorders are: Depression, Bipolar Disorder, Seasonal Affective, Disorder (SAD), and Self-Harming. Depression and Bipolar Disorders are mental disorders. However, physical illnesses may also affect a person’s mood, thoughts, body, energy and/or emotions. Both disorders, especially bipolar disorder, tend to follow a cyclical course, meaning they have ups and downs (in a cycle).
