I'm so sorry to read about this. Hope Eva can rest in peace.
I have a story about my friend too. When I was in elementary school, I have a friend, a best friend, and he died because of pain in his head, such as a cancer, i don't know. His parents didn't tell us. But, it was break my heart and our classmate.
So, I hope everyone keeping their health. Big hug @sirenahippie :)
