HI i do have stutter blocks too. >Also: I think it all started getting worse when we campaigned for the student council and I had to speak in front of every classroom of our school. Idk if that's related to my worsening stuttering tho Could it be because your anxiety level spiked? that's what i noticed on my speech blocks, whether i am extremely happy, extremely sad and mad it gets worse. If it's your nervousness or emotion that affects it what i could share is to try being calm.
