Children and teens have anxiety in their lives, just as adults do, and they can suffer from anxiety disorders in much the same way. Stressful life events, such as starting school, moving, or the loss of a parent, can trigger the onset of an anxiety disorder, but a specific stressor need not be the precursor to the development of a disorder.
