RCG,
I know nothing about dysautonomia, or it's symptoms.
That said, feelings of suffocating, the perceived inability to take in a full breath, and a general tightness associated with breathing are all symptoms of anxiety. I've experienced such symptoms, myself.
You might benefit from some breathing exercises, as foolish as that sounds when you're having trouble breathing. Sometimes when anxious, without realizing it, we change our breathing patterns. Either breathing too fast, or too slow. Not fully exhaling, or inhaling.
