I have the same thing and I avoid it the same way as poptart - just staying silent. It's hard though, because my mind is always racing. I agonize so much on what I'm going to say next that I just don't say anything, but then I feel like I'm being rude if I don't respond. I remember being introduced to someone and I was so unsure of what to say that I ended up staring at them silently until they walked away. I was bullied in elementary school because I had a "big mouth," but now I feel like I'll be bullied again if I try to talk. This has made me very shy, and I'm still scared after nearly 10 years. I was able to talk to an old classmate (online) and he said that everyone thought I didn't talk because I was stuck-up! The life of someone with social anxiety... I certainly wouldn't say any of this in person. I'd probably stare at the floor since I feel too intimidated to look anyone in the eye.
