How does depression show itself?

Not everyone who suffers from depression experiences the same symptoms or the same level of severity. Generally, a diagnosis requires that five or more of the following symptoms must be present for two weeks.

• Persistent sadness
• A loss of interest in normal activities
• Increased irritability and restlessness
• Feelings of hopelessness, guilt, worthlessness and helplessness
• Fatigue, weight loss or weight gain, lethargy and changes in eating or sleeping habits
• Difficulty concentrating, forgetfulness and indecision
• Suicidal thoughts or attempts, self-mutilation
• Persistent pain - such as headaches, stomachaches and digestive problems - that do not respond to treatment
• Worsened existing conditions, such as arthritis or diabetes
