Caldey Island

We come here every year and always visit the oldest chapel on the island. There is an opportunity for people to write out little prayers and messages to loved ones on small rectangles of card. Many of them are laid out to see. I spent too long sifting through pleas and prayers and messages to people loved and lost, and had to leave my family inside and sit under the sun for a while.
So much heartache, so much thanks. How to make sense of it all?
