My prayers- lighting a candle here in Cleveland. I hope some of the kindness you show comes 'round back to your ladywife as good health outcomes.
FWIW - Try to take advantage of whatever support networks are available in your area. Here we have "The Gathering Place." Other cities have "Gilda's Club" - places that offer resources to those who've had cancer touch their lives (themselves AND family members). It's much less scary when you've got others around you who are farther down the same road & you can see that increasingly, it's a road that is a return to health.
