I have so been there. What I did was practice in front of my bathroom mirror. I practiced greetings, I practiced every day sayings, I even practiced my name for days, for months, until it became boring. Until it became rote memory. Now, when it happens in real life, my rote memory takes over and it just comes out. When I think about it, when I think about having difficulty saying it, all those familiar emotions come back and I Stutter. What people don't realize is our daily struggle, our hourly struggle, our minute by minute struggle. Nike has the best slogan......"Just Do It"
