Anxiety disorders
According to the Anxiety and Depression Association of America, anxiety disorders are the most common mental illness.
People with these conditions have severe fear or anxiety related to certain objects or situations. Most people with an anxiety disorder try to avoid exposure to whatever triggers their anxiety.
Below are some examples of anxiety disorders.
Generalized anxiety disorder
Generalized anxiety disorder (GAD) involves excessive worry or fear that disrupts everyday living.
People may also experience physical symptoms, including:
restlessness
fatigue
poor concentration
tense muscles
interrupted sleep
A bout of anxiety symptoms does not necessarily need a specific trigger in people with GAD.
They may experience excessive anxiety when encountering everyday situations that do not pose a direct danger, such as chores or appointments. A person with GAD may sometimes feel anxiety with no trigger at all.
Panic disorder
People with a panic disorder experience regular panic attacks involving sudden, overwhelming terror or a sense of imminent disaster and death.
