i don't know how bad you are, but i was terrified. really, the only thing that got me through was knowing that i was already pregnant (even when we got pregnant) was that it was the only way i was getting a baby that i really wanted. then when i went to deliver, it was just knowing that i was dead set on NOT having a c-sect. and it's not like you could change your mind.
you are over thinking this whole thing far too much.
it really isn't as horrible as you're making it out to be. Yes you should seek help.
I wasn't unusually scared of labor or anything but i did end up having a VERY unplanned non-medicated birth and it really wasn't that awful. When the doctor told me it was time to push and i hadn't gotten the epi yet i was so scared i almost passed out but when it came down to it... I'd totally do it again.
Idk just keep in mind that your body is the result of several million years of fine tuning designed to give birth. You can do it and you'll have a beautiful baby for your troubles.
