This is the time you must practice the concept of staying in the moment. It is possible to control the anxiety with practice. Stay focused on the things that are real. Do not allow your mind to wander to the "what if's" The moment you slip to "what if's", then the awfulizing will start. If you feel it happening, close your eyes and focus all your mind on just your breathing. You will find that over time and with practice you can pull your mind out of an anxiety attack.

Take care
