Depression is a condition that negatively impacts the way you behave, feel, and think. It causes feelings of sadness and/or a loss of interest in activities you once enjoyed. Depression ranges from mild to severe and may cause difficulties such as sleeping, appetite changes, sadness, loss of energy, fatigue, feelings of worthlessness, emptiness, and/or guilt. It may result in trouble making decisions and concentrating, and having thoughts of death or suicide.
