I know in advance the words that trouble me (unfortunately, my name is one of them). I often have to hesitate and breathe and center myself, and I know people are looking at me going "Don't you know your own name?" As for the other words I have difficulties with, I am good at using synonyms (that was on another post). But sometimes I just get totally frustrated and smack the table or stomp my foot, and then peoples' eyes get big.
