I understand how you feel. My surgery was last Thursday and I felt the same way. My biggest fear was not waking up. I hate being put to sleep. It is the only thing I can relate to death. Let me tell you how I get over this fear. PRAY! God I pray for my sister in the name of Jesus. Remove all doubt and fear from her spirit, guide the hand of the doctor and the other caregivers that will be taking care of her. Lord forgive her of anything she has done that was not pleasing to you. Bless her to have this new exciting start in life. In Jesus nam Amen! You will be find it is already done.
