Understanding the Signs and Symptoms of Depression

The everyday occurrences of life can leave everyone feeling sad on occasion. From the breakup of a close relationship to career disappointments, it is natural to experience loneliness and related feelings of sadness. However, when the symptoms of depression begin to impact your quality of life, you need to take action.

Adults and teens exhibit somewhat different symptoms of depression, with some overlap in signs. Clinical depression can result in physical symptoms and behavioral concerns.

Extreme eating, either overindulgence or avoidance
Ongoing anxiety, sadness and feelings of worthlessness
Chronic aches and pains that don't have an identifiable origin and are treatment-resistant
Bouts of irritability, restlessness and guilt; helplessness
Fatigue
Digestive difficulties
