I cannot imagine the pain and frustration all of this has caused you and your family. I believe her progress is an answer to all of our prayers, which I know have kept on coming, and will continue to do so.
Hang in there brother, as you are not alone in this, as for us, we are simply trying to provide some help and comfort with our prayers, but the Lord, the Lord is with Chelsea, you and your family, and he will not leave you alone.
Keep the faith and hang on, and I believe I can speak for all here, remember even though many of us don't know each other, we are still here for each other, and in this case, we are here for you. More prayers coming for Chelsea, you and yours. God bless you and your family.
