While there is a distinction between fear and anxiety, for many people it is merely a matter of language. For example, I will say I have a fear of water when, in fact, what I experience is anxiety about being in the water.
Fear is a natural reaction of the mind-body system that is triggered by danger. Once danger passes, so does the fear response. The body calms down and returns to normal state of balance.
Anxiety bypasses the body, trapping panicky thoughts. The voice of fear paints scenarios of disaster that seem believable. And panicky thoughts can quickly become obsessive.
As anxiety takes hold it becomes more difficult to make rational decisions and the voice of fear becomes more believable. Rationality is bypassed; what you believe is what matters. And most of the time, what we fear, what we worry about never materializes.
Be mindful of your anxious thoughts. When anxiety or the act of worrying becomes excessive and all consuming, it may be time to talk with your primary care physician.
