I have a terrible time trying to do some public speaking. For example: I get training courses at my work alot and i have to go to them and often my "team" have to stand up and speak infront of the class. We all usualy get a shot at some point. Today i had one n i more or less volunteered myself for the last one cos i thought it should be a piece of cake.(Im in a band ive done 3 gigs each time i got on stage sometimes in front of a couple of hundred and done vocals and that went pretty well) But for some reason when i speak in a class room type situation I get the flight or fight reponse any idea why?
