Oh bless you. I was absolutely terrified of giving birth in my day (much older now) and I can really sympathise.
My own mother had problems with childbirth, she had an emergency section after a long labour and she nearly died. She did go on to have another child, but would regale my sister and I with terrible stories about it, in too much detail, and it ruined my view of childbirth when my time came.
I was afraid of the pain, afraid of losing my baby and honestly thought I might die!
If this sounds familiar, there is nothing wrong with electing to have a c-section. You can also have the epidural, which I had, and which was OK. I had no pain even though in the end I needed a forceps delivery, the epidural was awkward but perfectly manageable and they can administer top ups if needed.
For my second we had problems which necessitated breaking my waters and a very quick delivery. I gave birth naturally because it was so quick, not even any gags and air, and although the pain is very sharp when the baby finally comes out, it was quick and that was it. End.
It is worrying because it's an experience you haven't had before but the majority of births go fine, and you will manage it.
