Hi Michele, this is nini/Kathy, there is really not much you can do about
the before surgery jitters, and I dont mean to make it sound not serious, it is. Try to get as much rest as you can, you know everybody will be praying for you, and count me amoung them.
My prayers will be with you, I pray you will feel better after you recover from your surgery, I pray it makes a very positive difference in your life.
Take care,
Kat
