Just a couple of afterthoughts (from the other side of the globe, takes me a while to catch up with you all :-)
First, I refused to watch the birthing videos at the antenatal classes, eventually gave in to watching one at home, and still really wished I hadn't.
Second, after 6 days of induced labour, medical/drug areas, ending up seriously ill, and having the staff say "at least you had a NATURAL birth, and baby was fine"... I really was gunning for a c-s if I ever got the guts up (ahem) to have another one. But having seen so many friends try and deal with the aftermath of c-s, I realise it has it's own set of problems.
Finally, I had almost convinced myself I should try and go for a VB next time (which is amusing here as a VB is a beer of course :-) when I just read the biggest study ever of VBs against elective c-sections, with all complicated cases removed from the data etc.... and the risk of fatality to the infant was almost twice that of a VB, with an elective c-section.
That was all I needed to hear really. I realise it wouldn't be so cut-and-dried for everyone, but thought it was a something extra for the debate, if it's not already over!
Rats, can't find the link now... will come back with it if you're interested...
PS this sounds like a v. specific problem you are dealing with OP, I had something very similar and had "brief therapy" - not saying it'st he answer, but found it brilliant. Good luck.
