Katholyn, I'm so sorry. I'm praying that God will heal your husband in an awesome, dramatic way and that you'll both be strengthened and encouraged throughout this ordeal.
This is supposed to be an exciting period in your life, and I'm just so sorry that you've been dealt this blow. I don't even have the words to say. Just know that we all love you and will be praying for you and thinking about you as you go through this struggle.
