on youtube they have yoga classes etc that might give you breathing exercises or just breathing exercises. I really do think we forget to breathe and hold our breath from terror. I am sure this happens to me.
I wonder if my friend who has had horrible things happen to her such as loss of her little girl to cancer handles these things better because she is a singer and knows how to deep breathe. I never thought of it til just now. She never hyperventilates.
Love
