I'm so sorry. I can only imagine the crushing blow this all feels like to you.
Of course, none of us can really "suggest" anything to you. I'm certain, though, (especially right now with everyone having been sort of blindsided), that your neurologist will proceed expediently to help you in every way possible.
Hang in there! There are other treatments still available that may help you. Your neuro will know best, I'm sure.
Again, I want to somehow express my heartfelt empathy to you. Don't give up! It ain't over yet!
All the best,
