personally i have a fear like that girl of singing in public,and i thing that pisses me off the most is i know it makes no sense because between the Ages of 8 and 16 i was a Chorister in a church choir,i even was head chorister for 4 years and had to sing solo's in public(i even have done it in front of people i don't know many times around the country,and became Bishop's Chorister,having to sing in front of people at Liverpool Cathedral who i had never met)
but around 2002 i found myself feeling physically sick at the thought of getting up and singing infront of people,if some one trys to get me up on a Karaoke i literally try to change the subject and head for the toilet its totally irrational but i cant seem to shake it
