Mothers are insane. I can't share my mother stories with you - they're just too mind-bogglingly upsetting. Perhaps the office manager at the MD's office could help? I've ALWAYS had wonderful luck, either with a really good nurse or the office manager. Sometimes they can navigate the system in ways we couldn't fathom. And sometimes (not always - it seems to depend on the person and the atmosphere in the office) they really seem to enjoy helping - like they're trapped in their office and love the opportunity to make things run smoothly when they can.
