starting to freak out

Bo
39 weeks and have my repeat csection scheduled Monday 4/17 (3 days!!!!) This is our third child and third csection. Haven't had a baby in almost 10 years. Now that it's so close, anxiety starting to reallllllly kick in and now I keep thinking I'm going  have a panic attack at the hospital. Can somebody help bring me back down to reality? Please and thank you!!!!
Ps: prayers appreciated ❤️
