Omg I’ve been getting the blocks too!! I usually just have my regular stutter that on a good day, doesn’t give me too much anxiety. But I just started a new job and I’ve been blocking when using the telephone. It’s the worst time to block because the person on the line may think I’m pranking them or that we’ve been disconnected. I also notice that when I block, it’s a complete block. Like I can’t just pick a new or similar word. I’m just totally and utterly blocked from speaking. Hate forcing my words out. It’s like I have no breath even though I’m breathing perfectly normal. Ugh.
