I'm so sorry. My prayers and best wishes go to you and your wife. I will pray for y'alls pain and sorrow to be eased and recovery for your wife.
I think both you and your wife are heros. Beyond that, we don't always know Divine Purpose right away, and sometimes we never do. It's an article of faith to trust in events, and this will definitely put your faith to the test. However, that doesn't mean that you shouldn't find time to let yourselves grieve, mourn, comfort one another and be comforted. Time will heal, and our prayers are with you in that healing.
