We can only hope your parents’ timing of this disclosure was out of guilt and concern, given the illness of your child and a realization of our mortality. Your wife is overwhelmed, as I’m sure you are, too. A child’s serious illness causes severe emotional strain on the parents…the worry, the fatigue- I can relate to that. Please see if the Catholic chaplain or priest assigned to the hospital might have some recommendations for you; both with regards to your parents’ disclosure and providing pastoral care for you and your wife at this time. May St Raphael, patron of healing and marriages, intercede for you and your family.
