It sounds like you are pretty much explaining my situation. I have very little issues with talking about things that I am passionate and knowledgeable about but I have huge issues saying my name at a coffee shop. It seems like a lot of my issues stem from questions where the words I can say cannot vary much (like answering my name or asking a question). Also, thanks for talking the time for writing the pretty large response! I know my little writeup wasn't the best thing ever but you taking the time to write and share that means a lot :)
