Depression is more than feeling down or having a few bad days. According to the American Psychiatric Association, depression is characterized by long-term feelings of sadness that affect how you feel, think, and act. Often, you lose interest in activities you once enjoyed and find it difficult to function at work and at home.
Other symptoms of depression may include:
• appetite changes
• changes in sleep patterns
• fatigue and decreased energy
• difficulty making decisions or concentrating
• feelings of worthlessness
• thoughts of death or suicide
