Hi!
First of all, I'd like to tell you I am glad you are okay.
I think you did just fine!
Outside of our diagnoses, we are "human" and are "emotional beings."
I don't see anything pathological about your high anxiety under the circumstances. As far as you knew at the time, your life was being threatened.
I'd be more concerned if you did not show emotion.
Personally, I think you are being too hard on yourself.
You deserve lots of self-compassion!
