Hi Sandy,
What great news about the success of the treatments for your daughter !! You and your family must be ecstatic with joy and relief..I can visualize the happy laughter from your daughter!
Your daughter is young and resilient and this may be what was needed to quell any more severe bouts!
Your worry is so well understood, but as the others have said, live each day one at a time, live in the moment and be mindful of the joy that is happening now.
If things change, you will take it one day at time at that point as well !!
Use your energy to enjoy this wonderful outcome!

Hope4thebest
