Scared

Is anyone else scared to deliver? I've been through natural birth and two sections. I've never had complications during birth. I'm planned to have a repeat c section on Sept 2nd. I am so excited to meet our last baby but also terrified something is going to go wrong. I look at our older kids and they are so precious and perfect. I am so worried of something happening to me and leaving them behind. Is anyone else experiencing this fear? Anytime I have contractions I get really excited about baby coming but right after that the fear comes creeping in, mainly the fear of dying during the surgery. Is this normal? How do I get my fears under control? It's almost paralyzing and last night I had a severe panic attack because I thought I was going into labor. Help!
