Anxiety is a normal human emotion that everyone experiences at times. Many people feel anxious, or nervous, when faced with a problem at work, before taking a test, or making an important decision.

Clark (1993) has argued that the core disturbance in panic is an abnormality in thinking. When external or internal stressors cause an increase in physiological activity, this activity is noticed but interpreted in catastrophic ways ( such as ‘i am having a heart attack’). This leads to yet more Physiological activity, which only confirms the catastrophic thinking and so a positive feedback loop between cognition and bodily activity is experienced.
The psychodynamic model sees Generalized Anxiety Disorder as the result of unacceptable unconscious conflicts that the ego has blocked. These impulses are powerful enough to produce constant tension and apprehension, but since they are unconscious, the person does not know what the source of anxiety is. Psycho dynamist theorist argued that, to defend ourselves, we try to repress the impulses, but our defences are occasionally weakened and the Panic disorder occurs. According to Klein & Rabkin (1981), Panic disorder may be experienced later in life when a threat of separation is either perceived or actually occurs.
The behaviorist model as Clark (1993) noted, the cue associated with the situations in which anxiety is aroused can lead to it being
