I find these things really seem amplified because of the situation we are in... but I also know that you know that she no longer feels the pain that she did here on Earth. That she was so loved by the children she touched was quite a blessing... too bad the adults did not think this was an important enough reason to announce her passing. I think children often understand these things better than adults do, and they certainly understand them more than we give them credit for.
I know this has touched you deeply. Know you gave her the gift of your D7 - her wonderful, unconditional love. Hold that little bit of joy in your heart.
