Hello Graham! How are you? 
Thank you very much for the compliments. 
I think that, when we are talking in public and you're afraid, we see only our defect. Most of the time, the people don't even see it! 
Yesterday I passed the oral in English. First, I didn't want to go but then I began not  to care what the people might be thinking and I during it, I even forgot that someone was there, looking at me. That made me calmer and my accent wasn't so bad (like normally). 
The only problem was that I was sure that much of what I said did not fit my subject. It was just a little bit, I hope. But I finally have passed it!
