Hi Machelle,
I understand how you feel, I felt that way about a week ago. My surgery is December 5th, not as close as yours, but fastly approaching. However, I began to pray vigorusly, and I found that the Lord has rendered a peace in my soul, because He is in control. Remember that God is guiding that surgeons hands, and He is in control of all things. If you reaffirm your faith, and believe that He wants you to have this, He will bring a peace and calm to your spirit that no drug can bring. I will keep you in my prayers, and good luck. Kim
