MY MD closed his doors, and left me in the wind. Its really tough to find someone that is cooperative, and "gets it" one that doesnt make you feel dismissed or whiney.
Call the # on the back of your ID card, and ask for a list of local MDs that take their insurance. Call the NMSS and ask if they know of anyone that is helpful with dx MS patients.
Hang in there.

its scary to lose someone you trust.
