HI!
I've had two c-sections---the first was unexpected, the second was planned. It's not nearly as bad as you think it's going to be. Of course, surgery is risky and scary, and bad things do happen, but the vast majority of c-sections go smoothly, and moms recover very well.
I thoroughly enjoyed both of my deliveries. I was numb and relaxed, and I didn't have to work at all! Try to focus on the wonderful outcome of the surgery instead of the surgery itself. When you hear that incredible first cry, you'll forget all about the nervousness!
The babies, in Daddy's arms, followed me back to my room from the operating room and neither baby ever left my sight unless I wanted a break. They even gave my children their first baths right there in my room.
Afterward, you'll be in pain, but that can be managed with meds, even if you're breastfeeding (as I did). Get up and moving as quickly as you can, but do be careful. You'll feel a lot better after a few days, and that's when it's easy to overdo it.
The best advice I was ever given--for either kind of birth--is to buy Depends to wear instead of the big pads they give you. You'll bleed for a while, and those pads slip and slide around a bit. If you'll wear Depends, you won't have to worry about leaking on anything. It's WONDERFUL!
Hang in there, and don't spend too much time being scared. A c-section, while not the ideal, isn't the end of the world!
