I'd say you made a fair analysis over the cause of your stuttering. Pay a visit to a speech therapist, it should help. In the mean while, just follow some of the pointers I made earlier ( points A, B, C... etc in my previous comments ). It's should help relieve most of your stuttering. Don't worry about the implications of stuttering. It's just a temporary thing like depression. You have to work to get out of it.
