Scared, all of a sudden

Out of the blue, the last couple of days, I'm very scared about the surgery. I keep thinking, "What if I don't make it through?" I've had 2 major surgeries before this, which went off without incidents. So I have NO legitimate reason to feel this way, but right now, I've got a serious case of jitters. I still want the surgery very badly, but I guess I'm looking for confirmation that this is a normal feeling, and that people make it through all the time. Does Dr. Aguirre have a mortality rate??? HELP!!! Traci
