Depression

Depression:

a common, serious mood disorder characterized by persistent sadness, loss of interest, fatigue, and cognitive changes lasting at least two weeks. Causes stem from complex interactions of genetics, biology, environment, and trauma. It is highly treatable through therapy and medication, though it can severely affect daily life. Cognitive Behavioral Therapy (CBT) is a common non-medicinal approach.

  • Persistent sadness or "empty" feelings

  • Loss of interest

  • Significant appetite/weight changes

  • Sleep disturbances (too much or too little)

  • Fatigue
