what is the type of fear if ur fear is from the stage itself and being on or from the feel that all r looking at u or just the fact u feel u'll do wrong!!!
u've to focus on the subject (tragedy ,song, explanation,...)till u completely make a clear vision in ur mind so u start to trust urself,,,
then start step by step to talk in front of others at any site whomever they are and at any situation even that u did wrong till u overcome the fear of making mistake and hearing stuff,,,also lose the fear of new persons and different ages
then u start to go onto dealing with the fear of stage by the going up it and do ur work any way with butting urself in trouble to form the brave acts
this step let u continue in the whole life with this changed act but if u didn't u'll by time regain the same problem and lose the whole way u tried to b better and brave, also sometimes this can result on the develop of more problem if a wrong done happen,,
only it works if the person fear to b in front of many people than the facing and going on stage is the fastest way to get rid of,,,
