I know that words from someone else can't take away that hollow, sick feeling, but you're not in this alone. My wife and I lost 4. But God has a perfect plan for you and the Mrs. that we can't begin to understand. In His perfect time, it will fall in place. After we lost 4, we had 2, one of each 4 years apart, and have been blessed by them being sent to us to watch over.
Know that we're lifting you in prayer.
