Hi Brother! I have almost the same stuttering as you do. Mine is worse tho, but the feeling of weak tounge or weak vocal cords is my main concern with myself. Sometimes I feel as if I don't have the energy to produce words. During hard periods I also feel as if I'm not finding the right words, my brain feels scattered and all over the place. I have been told that anxiety can cause temporary cognitive decline. I swear that I feel dumber during an anxious period with alot of stuttering. I recently bumped up my Fluoxetine dosage and I can't hardly speak at all because of the increased anxiety. Also having problems formulating sentences. I don't hear that you are having slurred speech!
