Sadness is something we all experience. It is a normal reaction to difficult times in life and usually passes with a little time. When a person has depression, it interferes with daily life and normal functioning. It can cause pain for both the person and those who care about him or her. Doctors call this condition “depressive disorder,” or “clinical depression.” It is a real illness. It is not a sign of a person’s weakness or a character flaw. You can’t “snap out of it.” You may need treatment to get better.
Sadness is only a small part of depression. Some people with depression may not feel sadness at all. The illness has many other symptoms, including physical ones. If you have been experiencing any of the following signs and symptoms for at least 2 weeks, you may be suffering from depression:
- Persistent sad, anxious, or “empty” mood
- Feelings of hopelessness, pessimism
- Feelings of guilt, worthlessness, helplessness
- Loss of interest or pleasure in hobbies and activities
- Decreased energy, fatigue, being “slowed down”
- Difficulty concentrating, remembering, making decisions
- Difficulty sleeping, early-morning awakening, or oversleeping
- Appetite and/or weight changes
- Thoughts of death or suicide, suicide attempts
- Restlessness, irritability
- Persistent physical symptoms
Many factors may play a role, including genetics, brain biology and chemistry, and life events such as trauma, loss of a loved one, a difficult relationship, an early childhood experience, or any stressful situation.
Depression can happen at any age, but often begins in the teens or early 20s or 30s. Most chronic mood and anxiety disorders in adults begin as high levels of anxiety in children. In fact, high levels of anxiety as a child could mean a higher risk of depression as an adult.
