Hi, Sophie. Just a thought... do you have to stay in TN for your doc? I hope you don't mind, but I took the liberty of checking some locations "nearby", based on the distance from downtown Memphis. Here's a list of possible alternate locations, just based on driveability of about 2 hours or less:
West Memphis, AR (10 min)
Hernando, MS (25 min) - don't know what's here, but it was close...
Little Rock, AR (2:05) - a longer drive but possible?
Jackson, TN (1:24) - I've heard there's a good doc here but don't know who... sorry.
New Madrid, MO (1:52).
Just wondered if any are doable. Maybe someone can tell you if there's a good doc in any of these locations. Just a thought... I've experienced so much frustration on this issue myself that I really hurt for you. I just wish there was something more concrete I could do. Good luck!
