3. Life events: Traumatic or stressful life events, such as the loss of a loved one, a divorce, or a job loss, can trigger depression.

4. Medical conditions: Certain medical conditions, such as chronic pain or a thyroid disorder, can increase the risk of developing depression.

Diagnosis of Depression:

A diagnosis of depression is made by a mental health professional, such as a psychiatrist or a psychologist.
