While it may be the same answer you'd get from other TOLer's, it is the best, prayer and Scripture reading the promises, the Sermon the Mount, Psalm 23 because it deals with the Lord and you; bathing the word of God is refreshing, and it brings relief that is far above what we could think or ask.
Remember Paul said, "This one thing I do, forget the past and I move forward" you move forward singly and together as well, and when you do ask the Lord to open your eyes to the understanding of how the Lord is helping you and your wife.
