I hope you've made an appointment with the doctor. Can you talk about your anxiety more? What are you afraid is going to happen?

If you don't have a regular doctor, then what you can do is ask for referrals from your insurance company, and then call the doctor's secretary and mention that you have a fear of doctors. She may be able to direct you to the doctor in the practice who's best helping anxious patients.

Then when you see the doctor mention it to them that you have a lot of anxiety about seeing doctors, and they will likely be more sensitive and communicative about what's going on, what they're planning to do, etc.
