And I think one good way to build confidence stuttering is to practice stuttering on purpose, while you keep a smile on your face and keep eye contact. Then it will be easier to be confident when you stutter for real and the anxiety is actually getting to you. Try to practice multiple ways of deliberately stuttering with people, such as doing a block with a pause of silence, fast repetitions, and slow repetitions where you take a breath in between each one. Then you will be less triggered when you start stuttering for real
