I think you should feel real proud for taking a broken child and mending her back. Her joy for life is back, her spark is back, she is excited again.
In Judaism it is said: Saving a life is like saving an entire world. And in many ways, you had saved her soul.There are no words of gratitude that I can express as they fall short, much like that smile that your baby gives you at the end of a long day.
That joy you feel that fills you to the rim and makes you forget every obstacle. That smile is enough to make you move mountains.
From all of us,
Big hugs.
