What if your doctor lives in a different town and they won't return my phone calls or email?

I had to have a doctor because I am a diabetic, RLS, Goiter, Barrett's Esophagus, Hiatal Hernia, Back pain, 4 stents in my heart, etc, but I cannot find a doctor in my town that will take medicare and medicaid. And I need one here in my town. Most of the time I end up in the Emergency Room because I don't have a doctor here in this town. How can I get a doctor to take me on when the doctors don't want to take medicare and medicaid. It is almost like a bad name when you mention that you have medicare and medicaid. If doctors don't take medicare and medicaid what are we seniors suppose to do?
