Need some encouragement

I'm 37+5 with my second rainbow. I have a scheduled c section in 5 days and I can't stop feeling this ever lasting doom feeling. I have this feeling that my baby will pass before then. I didn't have this feeling with my first rainbow. It just keeps coming to my mind and I'm having anxiety about it. I'm praying that I just make it 5 more days. TIA I just needed to get that off my shoulders.
