Depression is a mood disorder that causes people to feel sad and lose interest in things that are typically enjoyable. People with depression may have difficulty doing daily activities, like getting out of bed, going to work, or completing household chores. Depression can also make people feel as if life isn't worth living. Although depression may be chronic and require long-term treatment, therapy along with medication can help! Below, I've outlined two types of depression I see on a regular basis.

Major depressive disorder

Some people have a single episode of depression while others experience recurring episodes. Symptoms of Major Depressive Disorder are experienced most of the day, almost every day and may include:

  • Feelings of sadness, emptiness, or hopelessness
  • Crying spells
  • Angry outbursts or irritability
  • Loss of interest in most or all typically enjoyable activities
  • Sleep disturbances, including insomnia or sleeping too much
  • Tiredness and lack of energy
  • Reduced appetite and weight loss or increased appetite and weight gain
  • Slowed thinking, speaking, or body movements
  • Feelings of worthlessness or guilt
  • Trouble thinking, concentrating, making decisions, and remembering things
  • Frequent or recurrent thoughts of death, suicidal thoughts, suicide attempts, or suicide
  • Unexplained physical problems, such as back pain, headaches, or stomachaches

Persistent Depressive Disorder (Dysthymia)

Persistent Depressive Disorder, also called dysthymia, is a chronic form of depression. This type of depression lasts for years and is typically not as severe as Major Depressive Disorder. Symptoms of Persistent Depressive Disorder usually don't go away for more than two months at a time and may include:

  • Loss of interest in daily activities
  • Sadness, emptiness, or feeling down
  • Hopelessness
  • Tiredness and lack of energy
  • Low self-esteem or self-criticism
  • Trouble concentrating and making decisions
  • Irritability
  • Decreased activity
  • Avoidance of social activities
  • Feelings of guilt and worry
  • Poor appetite or overeating
  • Sleep problems
