Adjustment disorder is somewhat related to Post Traumatic Stress Disorder, and is often argued over whether or not it should even be a diagnosis of its own. There are three different types of Adjustment disorder. Adjustment Disorder with Depressed Mood, Adjustment Disorder with Anxiety, and Adjustment Disorder with Depressed Mood and Anxiety. I have the latter. People with Adjustment disorder have symptoms of PTSD, but the stressor is usually not something huge, so people with Adjustment Disorder get traumatized at things that aren't exactly very traumatizing. The different types of Adjustment Disorder are for the different ways patients react to their stressor.
I got Adjustment Disorder with Depressed Mood and Anxiety after being sexually assaulted by someone three times my age.
