I'll be the first to admit that I regularly fall short in the eyes of the Lord, but I do believe that He will guide you through this if you let Him into your heart. I know it's so hard and I've asked the question why so many times myself. Be strong for your children and your wife and give yourself over to God when you feel like you can't take anymore. I can't say I know exactly how you feel, but I've walked a rocky path myself and I've experienced the frustration of watching loved ones suffer. Please know and believe this, prayer really is powerful, and we will lift you and yours up in prayer.
