Csection and panicking

After two vaginal deliveries, Ive been scheduled for a csection in two days and I am so scared I feel sick and I can’t eat or focus. My last delivery was a severe shoulder dystociaand my daughter was stuck a long time & ended with a broken humerus to release her from my pelvis and this baby is measuring bigger than she was at the same time which is 38weeks so for safety of the baby csection is the best route, I know it’s the best for the baby but I can not settle myself with this decision and I am so scared, I wish they could just knock me all the way out and just wake me up once she’s here😓
