family doctor question? who do I go through?

Okay, so I don't have a doctor, but I'm looking to find one. I know I have hearing loss because I've gone to the doctor before about it and I need to know, do I schedule an appointment though a family doctor first or can I go ahead and schedule an appointed with a ear, nose & throat doctor? I have to get a hearing aid, but I'm 22 and my moms done all the doctor stuff so I never had to deal with it so I'm a little confused on what to do first.
