Help me understand what's wrong with me. I have blocks/stoppages in my speech, I have no repetitions or prolongations. This happens in large group settings, it's worse when I feel anxious, it rarely if ever happens in a small group setting or with my family. It never happens when I'm alone.

Help me understand what's wrong with me. I have blocks/stoppages in my speech, I have no repetitions or prolongations. This happens in large group settings, it's worse when I feel anxious, it rarely if ever happens in a small group setting or with my family. It never happens when I'm alone. Objective of this post: I want to figure out what's wrong with me so I can figure out exactly what to do next to work on my block/stoppage stutter. My blocks/stoppages are worst in large groups, especially in a group setting where I need to raise my voice (such as being called on when I am sitting at the back of a classroom). It's associated with anxiety, for sure, in those large group settings. I don't have agoraphobia. I do great in large group settings where I know I won't need to speak loudly. I often think that if I had a microphone in front of me I spoke into, where I wouldn't need to raise my voice loudly from the back of the classroom, I wouldn't stutter. This is where I think anxiety comes into play. I think the attention of speaking loudly, eyes and ears on me, raises my anxiety and makes me more worried about blocking... and the cycle goes on. I remember one class my smart watch reported my heart rate was >100 for nearly 2 hours because the lecturer kept calling on people to answer questions and I was terrified he was going to call on me. I just got a prescription for a beta blocker a few days ago which I'll try at my next class where there is participation expected. I'm curious to see if it helps. Please feel free to ask more questions to help figure out what's wrong with me. I think if I understand my stutter better, then I'll be able to take better steps towards getting better. Thanks
