I don't suppose my opinion is of any interest, given that you have had so many.
But I wonder if you are basing your decision on information that isn't quite accurate.
Your body may surprise you, and be completely great at breastfeeding your baby, despite your concerns.
Your baby, on the other hand, may be intolerant of formula, or have problems with constipation and so on, if you formula feed.
Things can go wrong whichever you choose.
You are not a bad person for being worried about this, however please don't discount breastfeeding totally without ever having tried it, as it can be a really wonderful experience.
I'm not saying you OUGHT to try it. I'm just suggesting that if you do, and it doesn't work out, your baby will probably be fine to transition to formula - and if it does work out, you might find you enjoy it and your child gets on really well with it.
So I don't mind what you do, but don't make a decision based on fear of it not working, when many people have fed in your situation very successfully xxx
