Fear of an object or a situation is a very natural human emotion that all of us undergo on a day to day basis. The basic difference between a normal fear and phobia is that, a phobia is kind of an unreasonable fear that is not associated with evidence and that would subside eventually over a period of time. This kind of irrational fear generally does not have an impact on the quality of the person’s life. People with phobias try to avoid what they are scared of. If they are not able to ignore it, they undergo various physical and physiological complications.
