I only know my experience. I stuttered from 10 -25 yrs. old. I haven't stuttered in 36 years. I practiced a technique I believed in and joined a Dale Carnegie class where I had to talk in front of a class. Read, "How to stop worrying and start living". We worry about things that never happen, and we worry what others will think of us, when they're really only worried about themselves. I told people I was sorry, and I have speech impediment. Then when I knew they wouldn't judge me, I proved myself wrong. The power is in you. Make it happen. It's worth every bit of effort you have. It doesn't have to be forever.
