It comes and goes but happens much more frequently than I wish. I was once a great speaker I would have no problem standing up anywhere and speak to any amount of people; I've given countless speeches to countless of people, I was a true public speaker. But lately, I've had difficulty just talking to one person, I'll talk and usually it's at the beginning of a sentence when the word(s) won't come out. I try to slow down think about that I'm going to say but I already know what I want to say and I wind up just standing with an open mouth grunting in an attempted to get the word out. When that happens sometimes I even need to apologize to the person I'm conversing with and I have no problem getting those words out. In elementary school I had a speech impediment but thanks to my speech therapist we work through those problems. I feel so stupid when that happens because i know that I'm better than that; it makes me scared to speak quite often.
