I revived this thread. Hoping for more input ... for more hope. It is so very difficult to answer these questions when I didn't find answers myself. The emptiness of the answers and the struggle with the vastness.

My DC of ~5 wanted to know if the days will end. I asked for clarification to make sure child was actually asking that. Then told child, yes, there is always a new day. It breaks my heart knowing there will be more deeper serious questions coming.
