What is anxiety? People in our culture want to get the definition right. They want to know exactly what they have so they can do something about it. Many times people feel the sympathetic nervous response (the “fight or flight” response beginning with the hormone release from our adrenal glands that increase heart rate and breathing, and gives a burst of energy to our muscles: Biology of Fear) but don’t call it anxiety. They call it stress or discomfort. That is fine! It doesn’t matter what we call it, we can still do something about it!
