Yes, I dont like the fight/flight designation either. I'm
  acutely aware of my adrenaline. I deal with panic attacks, and
  have learned to gain some control over them with various
  techniques. Biofeedback training at 11 was the first step,
  adjusting my lifestyle around it as best I can is another.For
  me, my #1 response is freeze. Although, it's not really
  freezing. It's more like stuck in a feedback loop.
  back-forth-back-forth-back-forth so quickly that it appears to
  be freezing.   Thankfully, I'm usually able to mostly control it
  when it begins to surface; and I'm able to let it pass by
  (usually) as the symptoms last for about 20 minutes if I'm able
  to get to a quiet, calm environment. Still, it's 20 minutes of a
  form of hell but I can typically manage it.   t's also how I
  know that "I am not my feelings and I am not my thoughts"
  because they can both be guided by forces (like adrenaline) that
  are outside of my immediate influence.
