Have you attended the ABA's breastfeeding class, or are you a member? Your local group may be able to provide a lot of practical and moral support.
Does your hospital have a lactation consultant on staff? Getting an LC to come and be with you while you feed can be invaluable, especially if you've had issues with cracks in the past, as this suggests the latch or your technique may need some adjustment. A good LC will watch you feed and make some suggestions. She can also advise you on different holds (sometimes trying a football hold helps with the dodgy side), nipple care, and even osteo recommendations and that sort of thing. If you don't have access to an LC at the hospital, I would strongly suggest finding a private one - meet her, make a plan together and arrange for her to visit you in hoospital for those early feeds. I'm thinking also you might need extra help after a c/s? I know after DD's birth and the pph I couldn't sit up and that first night DD's latch was terrible as she was also tired and I couldn't sit up to hold her properly, and I had to spend the next couple of weeks reteaching her.

Good luck!
