How are depression and sadness different?

People who’ve experienced a loss, such as the death of a loved one, may describe themselves as being depressed. But being sad and being depressed is not the same. Grieving is a natural response while depression is a clinically diagnosable disorder. Here are some ways they differ:

  • In grief, sadness comes in waves and is often mixed with positive memories. In depression, mood and/interest (pleasure) are decreased for more than two weeks at a time.
  • Self-esteem is usually maintained in grief but in depression, feelings of worthlessness and self-loathing are common.
  • Sometimes grief can bring on major depression. When these two co-exist, grief is experienced more severely and lasts longer. But despite the similarities, grief and depression are two very different animals.
