We all have developed an aversion to a situation, person, or object. What creates fear is prior unpleasant experiences. There is a learned association between painful stimuli and the fear reaction. Upon repeated exposure, the same panic response becomes conditioned. This means that behavior is under direct control of the emotional system. It may feel as though there is no way to change the outcome. If the magnitude of the fear response increases, this may suggest the original trigger has been reinforced by additional compounding trauma.
