I agree with the others, you would be wise to see your family practice physician so you can receive an indepth medical screening exam to make sure your problems are not from a medical condition.
The list idea is excellent. Yes you will be nervous until the physician comes into the room then you usual feel better. It is the waiting that is tough.
A nurse will check you in so do not be afraid to tell her how scared you feel.
Good luck and gentle hugs.
