sunrise, the SE sounds helpful for you this time and I'm glad.

I haven't read enough about it yet, but what my T told me about Peter Levine's studies is that wild animals, after trauma, shake themselves and that's how they discharge the negativity. I wonder if that's what my T will want to do with me.
I feel better about it now that I know you're doing it with your T since you know I respect your T! Do you know what his training in SE is?
I'm sorry you're having all this the stress that makes your heart beat weirdly in the first place. I know how scary that must be!
Ts can handle our negative energy better than we can because it's OUR problem, not theirs. I know we debate on this forum about whether we are more than our T's "job", and hope that we are, but I think the fact that we are "their job" enables them to deal with so much negative energy every day.
