[quote="gdgt"]This happens to me when I feel overwhelmed by social situations (most of the time, unless it is someone I know very well). If I have to articulate too many thoughts at once, I just completely lose the ability to say anything coherent, and then I find I can't really speak at all. I'm usually so frustrated by this that I start to get emotional, possibly even start crying! This can be problematic depending on what the conversation is about.

This is exactly whatstarted happeniingto me about 5 years ago. I don't know if it was changing hormones, or incresing stress (I'm betting on the stress), but I suddenly started getting overwhelmed, then silent, and then sometimes an annoying crying jag, which is VERY unlike me. Grrr.
