ChristiB,We easily become our own worse enemy when we keep googling symptoms because the most serious causes of a sx similiar to ours is the one that sticks with us. When you notice yourself using a what-if thought, stop it
in its tracks. It
may help to visualize the word "Stop" in big red letters in your
mind. This action interrupts the thought. Then immediately change your
focus by replacing the what-if thought with the new, healthier thought you
created.
Try "I am OK " !
