My stutter is very similar. I’m in med school now and recently my disfluency has gotten 10x worse bc I’m anxious about my hospital rotations starting next month. My biggest concerns are being comfortable presenting to the doctors in front of other students and saying my name during introductions. I just started on a low dose SSRI (celexa, 10mg) a week and a half ago and i have improved soooo much. It is like night and day for me. My family has noticed and Im much less anxious about my stutter. I still have a little disfluency but it’s far more manageable than before. An SSRI might be a good option for you. The perpetuating cycle of stuttering and then anxiety exacerbating it is really horrible. I’m so happy I’ve found a solution that really seems to be working. If it’s an option for you it would be worth a shot.
