Depression

What is the difference between sadness and depression? 

Occasional sadness is a normal part of life. But, sometimes, the sadness persists longer than expected. 

When sadness doesn’t naturally start to lighten within a few weeks, or when your mood doesn’t fluctuate, it might be more than sadness: You could have depression. 

While sadness is an emotion, depression is a mental health disorder. Mental health experts typically diagnose depression when symptoms last at least two weeks and disrupt normal day-to-day activities.  

What are the most common depression symptoms?

Depression can cause a broad range of symptoms and may affect everyone differently. Some of the most common depression symptoms include: 

  • Sadness that persists most or all of the day on most or all days
  • Loss of interest in things you usually enjoy
  • Lack of energy
  • Irritability
  • Inability to concentrate
  • Feelings of guilt
  • Feelings of worthlessness
  • Frequent thoughts about death, possibly with suicidal ideation
  • Sleep habit changes (insomnia or sleeping far more than usual)
  • Eating habit changes

These symptoms aren’t exclusive to depression. Other mental health disorders, like bipolar II disorder, feature long episodes of a depressed mood as well.
