Adjustment disorder is a condition that may be diagnosed when an individual experiences a shift in their mood and/or personality due to a recent and significant change. This period of adjustment may be due to a traumatic or stressful event such as marital problems, divorce, or loss. When an individual struggles with adjustment disorder, they typically experience stress and feelings of depression and hopelessness. Learning how to cope with a significant change in healthy ways is essential to dealing with your emotions and avoiding unhealthy coping behaviors.
