Dedication?

Either she is a serious workaholic or she is being blackmailed in some way that she feels she must continue on no matter what the cost.

In either case, this girl needs a vacation. If she works herself to death, what is all the money good for?

She sounds scared to death to NOT perform as expected. What could drive someone to put their career above their own life? Surely she can tell that if she continues like this she will not survive long.

Someone needs to get to the underlying cause of her "Dedication" before she ends up actually killing herself.
