Time heals the mind. Sounds like she's already moving ahead, everyone has to set their own pace to build confidence. Just let them know your door is always open, and they won't get any negative feedback by consulting your advice. Example: Analytical criticism is OK, it's reality. Negative personal opinions are not, they'll just destroy what confidence has been gained so far.
She'll be ready to ride more and more as time progresses and her confidence returns, be supportive. Seeing if she can keep up a hgh speed pace in twisties is not a good way to build confidence, make it fun when you go riding but not too competitive.
Good Luck,
