Anxiety vs. Fear

"Anxiety for people who don't have anxiety is simply fear. But fear is much more complex for people who live with anxiety. For starters, anxiety is genetic. I didn't learn that until much, much later in life. Anxiety comes from deep within your own body, and when it flows out it's almost impossible to control on your own."
