Doc, you've lifted up so many of us in the Gang with your encouragement and prayers, it is only fitting for all of us to lift you up to our Lord, the Great Physician. He's got this one, Doc. He's got you in His hands and He's gonna carry you through this situation!
I know you must feel like you just have to do more to fix the problem, because you can't just sit back and do nothing - it's not your nature. You've been taking the right steps, in the right direction, with His wisdom. And the Lord knows we don't always get the answers we want, when we want them, but His timing is perfect and His path is straighter than our own.
Hang in there Doc, we're praying for you.
