There are various types of anxiety disorders, including generalized anxiety disorder, panic disorder, and social anxiety disorder. Symptoms can include restlessness, rapid heartbeat, and difficulty concentrating. Treatment options often involve therapy, medication, or lifestyle changes to help manage symptoms effectively.
