I am all to familiar with your storm. My daughter recently had 3 surgeries within a month. The last surgery left her with two tubes.....not a sight a parent want to see with their child.
Through it all, I had to depend and focus on the promises of God found in His Word, and especially on the character (attributes) od God. HE is a Healer, a Comforter, a Keeper, a Sustainer and so much more.
Philippians 4:6-7 says, Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
Don't worry, but tell God your struggle. He will give you such a peace that will keep your heart from being troubled and your mind from going crazy. My little one was in the hospital eight days, and the peace God gave me allowed me not to miss a meal! He is able....Is there anything too hard for God?
Praying for you
