Anxiety disorder is also known as generalized anxiety disorder. Anxiety is one of the normal human emotions. When individuals encounter some tasks, frustrations, stress, disasters, separations, choices, etc., it is normal to experience anxiety and has some positive meaning. However, the anxiety of people with anxiety disorders is clearly excessive and exaggerated, and it is also ineffective. It significantly affects the individual’s life, work and study. Anxiety is experienced primarily in terms of both mental anxiety and somatic symptoms. Mental anxiety manifests itself as an individual’s excessive fear and worry about many upcoming events, such as worrying about work, school, health, etc., nervousness, irritability, difficulty concentrating, and reduced thinking ability. Physical symptoms include muscle tension, shivering, sweating, insomnia, fatigue, decreased appetite, fidgeting, walking back and forth, smoking, rubbing hands, and other nervous behaviors. Most patients with anxiety disorders have a prolonged illness, constituting a diagnosis that lasts for at least six months. Individuals with anxiety are so stressed and distressed that they even induce depressive experiences, feel worse than death, and even develop suicidal ideas and behaviors. Patients are sometimes accompanied by depressive disorders.
