If you find your stuttering is getting worse, check in with your environment. Do you find there are additional environmental stressors? These could include changes in school, job, or a social circle. These stressors could also be in the form of additional responsibilities on you, due to an increase in workload. Overall, when you find that the demands of your life exceed what you understand to be your capacity, it may be difficult to keep up. In addition to environmental stressors, check in with your speaking pace. Do you find that your mouth speaks too fast for your brain to keep up? Each sound that we produce is a result of airflow that has been shaped by our tongue, teeth and or lips. Perhaps slowing down and thinking about each sound that you are saying will allow you to improve your fluency.
