When you are confronted with a stressor, both the mind and body react, resulting in anxiety symptoms. You respond with a survival reaction, called the fight or flight response, which initiates acute changes in every organ, muscle, and limb. Basically, it is the nervous system's response to stressors that triggers anxiety. Anxiety is a natural human quality, but your body and mind can also overreact. The question is: how can you tell that anxiety has ceased to be a normal human reaction and become a chronic problem?
