I know this all seems rather dry and academic, but understand what you're doing when you make the conscious decision to face those fears, whatever they may be. You're bringing what you fear out of your emotional center and putting it in its proper place, up to your rational, analytical mind. This allows you to engage in active coping, to analyze your stressors, dissect them, and then defeat them, piece by rational piece.
Women are still relatively new to mainstream law enforcement, and sometimes it seems as though we have so much to worry about, whether it's tactical, administrative, or personal. Don't let negative visualization set you up for failure. Know your strengths and learn to take advantage of them, and when you encounter something that seems to create a fear response, look it right in the eye and say come on, gimme a hug!
