One day her hand is numb. Then she's feeling grumpy and paranoid. Then she loses her appetite and can't sleep. She goes to doctors who tell her it's nothing or prescribe anti-anxiety drugs that don't begin to touch the problem.

When things finally reach a breaking point and she's admitted to NYU hospital after having seizures, she's finally diagnosed with a rare autoimmune disease which, if untreated, can basically destroy the brain and leave patients greatly diminished.
