Pre-Op Question

:confused:I am 5'1" tall and weigh 280lbs. My goal weight is 130. I have gone through all of the weigh ins and even got it added to our insurance and was approved to have the surgery and was scheduled to have the surgery on January 21st. I started having 2nd thoughts and was praying that if this wasn't the right thing to do then show me a sign. My surgeon called me from his cell phone on the Sunday morning before my surgery and told me he was stuck out of town and we would have to reschedule it so of course this really scared me. My concern is the fact that I've had 5 (FIVE) major abdominal surgeries in the last 8 years and I'm concerned about tissue scarring and just the fact of having another surgical procedure. I've had 2 C-Sections (first one emergent), 2 Hernias (1 right inguinal and the other an incisional hernia), and my Gallbladder removed. Has anyone else had several surgeries and still had the procedure?
