Fear of surgery

I’ve had plenty of surgeries in my lifetime since I was little. Every single one of my surgeries were successful and absolutely no complications before, during, or after. I’ve never be scared to have any of my surgeries. I have a surgery next week to remove hardware and it’s absolutely scaring me. I am having a fear of dying during surgery and I don’t know why. I think I’ve chalked it up to my daughter. I think im having this fear because im afraid that if I get this surgery I’ll die and leave my daughter without her mother. This is my first surgery after giving birth over two years ago. Please, is this normal? Or could it just be an irrational fear?
