I remember waking up the morning after giving birth, glancing at the door to see who was walking into the room, seeing a baby sleeping in the crib between my bed and the door and thinking "OMG, there's a baby in the room ............... and it's OURS!" (and then wondered "What the hell happens next?").  If I had to describe the moment I felt complete loss of control, that would have to have been it.  Weird really, as like you I'd been worrying about other "what ifs?" during my pregnancy.

One thing that helped me prepare for, and feel OK about, labour and birth was reading "Ina May's Guide to Childbirth". It has heaps of positive birth stories and tips for getting through labour, trusting your body etc.  Also talking with my midwife ... she banned me from Google searches lol, and was always willing to answer my questions, no matter how stupid I thought they were.  Being a bit of a control freak, trying to accept that I wasn't going to be able to have complete control over the labour, birth, breastfeeding or bubs sleeping etc definitely helped me.   It's not always easy to just "go with the flow", but something to keep in mind if you can.  Actually, during labour I think my body ordered my mind to "just shut up" (which for once in my life it actually did) - sometimes avoiding thinking/analysing too much is helpful too!

All the best for the next few weeks .
