No better place to let it all out than at the doctors. The visit might have been on your mind. Hence you are feeling so bad. But let your doctor exactly how you are feeling. She won't send you for any tests there and then. Fear not about that one. I am sure she will be very aware that it is just your anxiety acting up. She is a doctor. I am sure she has seen and heard it all before. Try and keep that head up and try not to worry.
