Thanks! It sounds like these are precursors of feeling so unheard that getting angry is about to happen if it hasn't already started.

Would there be time to notice these particular signs and step back from whatever is going on?

In other words, would you be able to quickly tell yourself "My heart is racing, I need to take a break right now," or "I am feeling anxious in my stomach, I need to take a break right now," or "I am swallowing a lot, I need to take a break right now"?
