From "Anxiety Disorders and Phobias - a Cognitive Perspective" by Aaron T. Beck. M.D. and Gary Emery, Ph.D. with Ruth L. Greenberg, Ph.D. (1985):
"When a person has anxiety he experiences a subjectively unpleasant
emotional state characterized by unpleasant subjective feelings, such as
tension or nervousness, and by physiological symptoms like heart
palpitations, tremor, nausea, and dizziness... Panic is an acute state of
anxiety associated with other dramatic physiological, motor, and cognitive
symptoms. The physiological correlations of panic are an intensified
version of those of anxiety - that is, rapid pulse, dizziness, cold and
profuse sweating, and tremor. In addition, one has a sense of impending
catastrophe, pervasive inhibitions, and an overwhelming desire to flee or
get help."
