social phobia

I was giving a talk the other day, to an audience of around a hundred or more people, some strangers, some colleagues and I was really enjoying myself. I was moving around the stage, joking, ad-libbing even, making eye contact.
I am determined not to allow myself to be limited by my fear of interacting with people. Whether I was born with an inclination towards social anxiety or whether I happened to develop it, I'm desperate to overcome it.
Today I am feeling extra brave. More surprised than impressed with my own bravery, I decide to leave the queue and explore the rest of the food stalls. 'Fish and Chips' was the first one on the corner and on my way home.
