Well...I've had panic/anxiety for most of my life. But I have had periods of relative calm. From what I have read and gotten from therapy, the extreme rush of adrenalin we get that causes most of our symptoms does have it limits. The gland can secrete just so much. Uncomfortable, scary but very rarely dangerous. Most attacks peak then slowly wane. Maybe that's what you are feeling when you describe being 'all panicked out'. That's what happens to me when I've had an extreme bout of attacks.
I once had a therapist tell me that when I had palpatations it was the same as someone running on a treadmill in a gym for twenty minutes and I was getting the same cardio vascular work out for nothing!
