Doctor's Visit Tomorrow

I have an appointment with my headache specialist tomorrow... probably the last for another 6 months.

I am really worried that I won't be able to tell her everything I'd like to. I tend to freeze in front of doctors and simply answer yes or no questions. Even with these questions, I tend to minimize the magnitude of symptoms.

Result: I always leave dissapointed, mad at myself, and get little or no relief.

Does anyone else have this "fear" of doctors? Does anybody have any suggestions on avoiding this happening again?

Thanks a ton!
