As Nanci said, you haven't made any more, or any worse, mistakes than other people have! I was so excited over the first snake I bred that I pestered her too much and stopped her laying, I felt so bad over it but I learnt the hard way not to do that again. No-one here is perfect with no mistakes ever in life, but we all pull together to help out and support each other.
Personally I'd advise not breeding your girl next year, leave her to mature another season and then you'll both be ready and hopefully be raising your own little hatchlings!
