I had anxiety with it too. Caused my mind to freeze and instead of thinking about perspectives related to the conversation, my mind went racing after itself to try and catch up to the conversation I suddenly realized I'd lost complete track of and I knew there was no way I could form any kind of intelligible response. Heart racing, rise in blood pressure, and always, the inevitable feelings of utter stupidity and failure. Pretty bothersome experience. It sounds like you have seen a doc?
