Well u literally explained my situation...like 99.99% i am 24 now i am still facing the same issue till now....but little do i know that i can say my name easily now.. I think the main thing is our breathing pattern.. did u every notice when u want to speak at that time you cannot breath at some moments and in those moments you stutter.. You have to work on ur breathing.. the more u breath calmly when you speak the more your stutter will end.. I am trying on my breathing patterns now.. i am trying to get a breathing pattern that helps to reduce the amount of effort that i put when i speak some certain words.... Some therapists say that you should speak while breathing out.. i tried that it is hard.. But i noticed that i speak when i take a breath in .. And i cannot breathe afterwards....I am trying now a lot to overcome this...
