'Anxiety' is another name for fear.

More exactly, it's repressed fear try to push itself into your conscious mind, from its origin point in the subconscious.

Rather than trying to push the fear away, its useful to identify and name your fears.

"If we answer the question - what is the anxiety trying to tell me - we begin to address the cause. This may mean some change in the way you life your life, but this change does not necessarily mean that you become less competent, or less valued, rather, it means that you begin to value the wisdom of your psyche more than before. By addressing the causes of the anxiety and making lifestyle changes, the anxiety should diminish, having achieved its goal - leading you towards a more full, balanced lifestyle."
