Symptoms of Anxiety. Symptoms of Anxiety: Introduction. The symptoms of anxiety are due to the body's reaction to stress called the fright, fight or flight response. This reaction developed in early human evolution as a means to increase alertness and readiness to react to dangerous stressors, such as the threat of a man-eating predator.
