Anxiety disorder?

I want to know if I have an anxiety disorder so I want to ask my doctor at my yearly checkup. I’m under 18 and my mom really does not believe in anxiety disorders being anything more than a bad attitude. Is there a way my doctor could keep it confidential until she knows for sure whether or not I have anxiety, so that my mom doesn’t think I’m being dramatic? And also what should I expect when bringing up anxiety? Do they usually recommend a psychiatrist?
