She may or may not ever be able to dance full-time again, but she said she was looking for a company with a less strenuous schedule -- like Weese, Korbes, and Orza did when they came to Seattle -- which she also said was something that Martins' "no" allowed her to consider mentally. Psychologically, it's not that unusual for people to have a fixed and focused goal when overcoming a life- or career-threatening illness or injury, and a return to NYCB maybe have been a single-minded way of getting through the worst. Being a college student with the kind of fatigue she was suffering is not a recipe for learning well.
She has been dancing locally, and that's a continued option if a full-time company does not take a risk on her. She has plenty of time for college and/or re-training.
