Last year my family doctor quit from the hospital to open her own practice but unfortunately she’s not in network with my insurance

I called the hospital to get an appointment (for a regular check up) with another doctor and none of their doctors 15 miles from me (2 big clinics and 2 small clinics) had any free appointments from May to December. The closest one was about 50 miles away with and the appointment and the waiting was 4 months
