Hey Ally,
Wow, you certainly have been put through the mill and then some. I'm so sorry you have had to go through all this for so long.
I am so happy you have found a wonderful caring neuro who is willing to sort this all out for you. It looks as though you have enough evidence, if you will, to finally get a diagnoses of MG so you can start treatment. I only hope the tests for this other disease come back negative. Waiting for results is so stressful, so I hope you'll know soon. I'll be keeping good thoughts.
Hang in there and know we are all here for you. Take care.
Big Hugs,
Pat
