Fear is an emotion that I experience very often.  Naturally this is during exams and subsequently while waiting for the results.  However there is one occassion when I was paralyzed with fear.  This was when I was doing my M.A.-I, and we had a series of student lectures.  I was one of the participants and my lecture happened to be the opening lecture.  I had been confident all morning, about twenty minutes before the lecture, my confidence started failing me.  I felt my heart go cold, my lips go dry and I was really paralyzed.  This incident of fear is still fresh.
