I remember the feeling as my first was born in hospital, too. I'm not sure what to say, since I had a birthplan like you, but still ended up with a highly medical birth. By the birth of my second I was ready for homebirth and it was great -- even in my tiny, cramped, way less-than-perfect living quarters. But I wasn't ready to take that plunge with my first, so I can understand your hesitance, your feeling that things have to be a certain way before it will work.
Have you made any progress in finding a midwife or doula who's not tied to the hospital, who could be with you and help you assert yourself when you're in a vulnerable place? That's one thing I didn't have that I wish I did.
All in all, just remember that soon you'll be holding and nursing your little one, and everything'll be all right!
