The physiological reaction to fear and anxiety is designed to prepare you for flight or fight. The difference is that in fear there is a physical object threating you. In anxiety, there is no physical object. However, the threat is real – preparing your mind and body for defense. In fear when the physical object disappears the body returns to normal function.
Anxiety is the result of your fear of the unknown – no object for you to see. To restore the body (via your mental fight or flight), you need to manifest a surrogate object. A technique I find helpful is to write down your feeling of the threats. When you visualize – the fog lifts, and you can determine how to handle and minimize the menace. The danger is the unknown. This alone is responsible for heightening anxiety. The solution is to unmask to eliminate these foreboding.
