I know it is painful, but you will grow strength against it over time. I spent most of college too scared to even start a conversation with my professors. Eventually you realize that man is the sum of his actions, not the useless noises that come out of his flapping lips and throat vibrations. No one cares that you stutter. They have plenty of other issues in their life to pay attention to yours. Granted, our issue is very visible and audible and can't be hidden. Become the inspirational stuttering public speaker that future stutterers will look up to like John Stossel, Elvis Presley, George Washington, and Marilyn Monroe.
