I did the same. The guys on here gave me the advice that what I thought were deal breakers wouldn't be. And I didn't believe them until the CO finally said he'd approved our visas!
It's normal to stress but,
@SusieQQQ has said something along the lines of, they WANT us to get these visas. So, unless you have made an unforgivable mistake - like forgetting to mention a spouse and / or child - or you are a thoroughly untrustworthy character and have a long criminal record.... you're golden.
We had a few mistakes in our eDV that we had to correct in the DS260. We had to get birth certificates and marriage certificates corrected because they weren't consistent with each other. We had to get new passports. All of which I thought would throw us into AP at best, denial at worst.
Not a single one of those things were mentioned at interview. Just be honest. Give them what they are asking for in the DS260. And ask us if you have any concerns.
