C section again

Hello everyone this is my second and last pregnancy. I’m having a scheduled c section on 1/18/21 and it’s a boy. This is my second child my first was also a c section but I went through a lot with my first one. That’s why I didn’t want more kids fear of pain and my anxiety is so bad. But anyways I only have about 3 weeks and a few days left to go. I’m going to be blunt I’m scared to die while having my c section and not coming back home to my son and leaving both my boys behind with no mother. Any advice how I can try to relax? I’m so terrified
