Panicking

I know I have made the right decision to have a repeat c section but since I scheduled it this afternoon I have been completely panicking. I’m on the verge of a full blown panic attack and I don’t even know why. My daughter is now five and I told my husband having 20 minutes to think before it happened was so much better than a month. I don’t even remember what it was like I was so exhausted. I just want to catch my breath and go back to sleep ? anyone else terrified of having another c section.
