I love reading, this is something that resonates with you! Breathwork is so so powerful.
But...you must be very mindful when working with traumatized clients...! When I started implementing breathwork with my clients, I had a very unpleasant experience. It taught me to be very mindful and observing well my clients, when going into breathwork.
It was just three deep breaths, exhaling with a sound/tone like a ship makes, when entering the harbor. She almost fainted, felt dizzy and nausea. She hadn't breathed since many years that deeply. It was just to much at once.
So it was a big lesson for me... You can get traumatized by going to fast to deep...Because that is exactly what happens when someone gets traumatized. Something happens to fast, to strong, to sudden.
