Bless your heart, I think I was terrified with the first one but one way to look at it is that it doesn't matter whether you are scared or not, it is happening and the best thing you can do is try to make sure it is as good as you can make it.
I wound up being induced with the first one and having a c-section after 14 hours. It was not the most pleasant experience but by the time the decision was made to do the c-section, I wanted the baby out and didn't really care how that happened. Get the epidural. Natural child birth is still natural with the epidural and it can make a huge amount of difference, what is most important is having energy after the baby is born and a protracted labor without medication leaves you totally wiped out even more than you would be with the epidural.
Now, I didn't mention my first experience to alarm you and if this has just freaked you out, I apologize but my point is that I had three children, had three c-sections, and if the first birth had been uber awful, I think I would have had a smaller family, lol.
My other advice is to be your own advocate or make sure you have someone that is not intimidated by hospitals. I had a friend who was a nurse, and instead of doing what I asked, she would tell me well that is the way they do it, not. The pitocin i.v. for example, made my arm feel terribly cold, which sometimes happens and I said they need to slow down the drip. Well, that wasn't an option but the nurses can bring you heated blankets that solve the problem. If you are uncomfortable, tell people and they will do the best they can to help take care of the problem. They know how hard you are working and in most hospitals, everyone is really nice and helpful and encouraging so don't feel like you are alone even if you don't have family surrounding you.
My second and third child they scheduled c-sections so I never really went through much labor except with the first and induced labor is different than natural labor because instead of progressively building the contractions, you go from not much to pretty much full-blown labor. With my youngest, I did go into labor but with none of the kids did I ever dialate beyond 3 cm, funny, to have three kids and still feel like you have never "had" a baby because none were delivered vaginally.
Oh, and post delivery, get a recliner if you do not have one. I don't know about other folks, but the worst thing for me after I got home was getting up in the middle of the night and forgetting to roll sideways to get up. After pulling those stomach muscles, it was terrible. With the second baby, I slept in the recliner for a couple of weeks and it was really helpful in terms of my incision pain. If you have a c-section take the pain meds. Some people are worried that they will hurt the baby and they do not go through the breast milk and you are better off taking the medicine and being able to do what you need for the baby instead of having the same activities wipe you out because you are in so much pain.
Also, before you go to the hospital give yourself a wonderful long pampering bath. Make sure you take a robe and do as much walking around the halls as you can, helps you get back on your feet and take better care of the baby. I would also recommend allowing the baby some time in the nursery so you can just rest because when you get home, the extra hands at the hospital aren't there.
Also, I usually had no help and wound up doing laundry and things when I really shouldn't have done them so when you get close to delivery, make sure all that kind of stuff is done so you really don't have to do anything but take care of baby and wash a load of baby clothes when necessary. If you don't have one, get a parenting magazine subscription because they have numerous helpful tips for every age child you could be dealing with. Baby wipes are your friend, keep them in more than one room of the house and your vehicle and also cloth diapers are great to function from burp rags to just plain rags to clean up whatever is coming out of baby.
