Have you talked to your speech therapist about factors that influence your stutter? And how it might be more than just "mood"? I mean, I'm not trying to make you worried or anything, but perhaps there's need for more medical examination. - Btw. this is sort of an aside, but in the interest of health: You're talking about [kinesiology](https://en.wikipedia.org/wiki/Kinesiology), and not [_applied_ kinesiology](https://en.wikipedia.org/wiki/Applied_kinesiology), right? (The latter being pseudoscience.)
