I'm sad too. I did have some speech therapy in school when I was really young and I have tried so many techniques since than. Through research I came to understand that it is a neurological condition so nothing I can do will really fix it. What helps the most is to just explain to someone right away that I have a speech impediment and than my anxiety is calmed and I stutter and block less. That doesn't always work though sometimes the person will laugh at me and be a jerk. So we just have to be some really emotionally resilient people to live with this condition.
