My worst years were teenager and into college. After graduating and setting down, my speech got better (no speech therapy) with confidence and less stress and anxiety. My speech got better as i accepted myself and my own limitations. Also my job requires me to communicate (meetings and presentation) on a regular basis with my team and to manager and directors. Even with my stutter, i am probably the most non-introverted in a family of introverts. I need to order food and take care of things over the phone. Also i volunteer for an org and had to give speeches in front of the City Council and other local politicians. All of this while being a stuttering. You can learn to live with your stuttering disability. You can enjoy your live and live fully.
