Yes, I have Block Stuttering too. For me, it tends to become less frequent when I don’t pay attention to what I’m saying, I just let words spill out. But if I’m reading something out loud, or reciting an event, it becomes very severe. Just try not to think about things you say, and whatever comes to mind just let it flow out. Whenever I experience something like that and I really need to say it, I’ll skip the word or use a different word that means the same thing. (Eg: Mad or Angry.)
