I would not mess with any drug unless it's something to treat the MG. Prozac, while widely taken, is not a benign drug and I also take a bit of offense by thinking that drugging you to blunt your feelings of mistreatment is also mistreatment! Of course you are anxious--who wouldn't be? I am not saying anti-depressants should not be used at all with MG, but to have a doctor just offer them when nothing for MG has even been tried seems premature and inappropriate, especially since Sarah even said she does not feel anxious.
Have you been a real "squeaky wheel" to the neuro? As in calling every 2 hours for your medical records or a call back or anything? If not--start!
As for having someone to treat you, I am assuming you will not be staying with your current neuro? If not, I would suggest you work on finding a new one as unless your primary has loads of experience with MG, he likely isn't the best qualified to treat you.
Hang in there!
