I understand completely - if I have to speak in front of more than a few people it hangs over me like a black cloud from the minute I find out about it! I have to speak at a public meeting tomorrow and am dreading it. I get a dry mouth, sweaty palms, hold my breath and so can't speak right. Plus I'm hopeless at speaking off the top of my head so try and memorise material! It's so exhausting - I can't wait until it's over.
