I'm sorry I don't know this, but do you and your T ever touch.
This doesn't necessarily require touch, but it's something L and I do to get me back out of freeze. She calls it "falling out breathing". It's basically tensing your muscles plus breathing. You breathe in as much as you can and tighten every part of your body. You count to ten and let all the air out. And then you shake off (literally move/shake) of the energy. She said something like dogs do that to reset their energy? You can also focus the muscle tension on certain parts where you're holding the emotional pain.
L and I hold hands during this.
