I have no experience, so no advice, I'm sorry. I guess the only thing I can suggest is a counsellor for you and your daughter.
I did have a friend go through something similar and she said she was shocked at the birth how much the baby looked like his 'father', and as a result she struggled to breastfeed. She has a fabulous bond with him now though, and is doing great.
You are very brave and I wish you all the best
