Goodness Raney I agree with alleycatkate. I think you are a nice person and perhaps they took advantage of your niceness.

I am not nice and would have demanded a piece of paper and would have written right then and there that I insist on seeing the DOCTOR WHATEVER that I made the appointment to see and not a substitute.

The nerve of the practice to assign your treatment to a nurse practitioner. I don't mean any disrespect to np"s and they are mostly wonderful in what they do. But this disease is serious, you have a mess of special issues and you should be treated by a doctor.
