You are on the right track. Go deep within. Those who suffer most when they are young. Grow the most in old age. Think of the infinite universe. you are but a spec in a never ending sea of stars. How important is it for you to cure your stutter? You are insignificant and so is your stutter. Believe that and with practise you and everyone you come in via tact with will to. Tell them you stutter but do not feel insecure. It sounds difficult but why should you feel shame for who you are? Stutter away! Until you forget your stutter was a problem at all.
