If you haven't seen this meltdown by an indie author, I highly encourage you to check it out. (http://booksandpals.blogspot.com/2011/03/greek-seaman-jacqueline-howett.html)
Perfect example of why people don't always take writers seriously. Truly shocking behavior, I think we can all learn a valuable lesson from this. One, always make sure you are sending out the best possible product. Can you imagine sending a query to an agent and then quickly backpedaling with "Oh no, that was the wrong copy, please read this instead?" I'd imagine that's instant form rejection territory. And two, no matter how precious your work is to you, you can't protect it forever.
Not everyone will like your writing. Or my writing. But on the bright side, we're in good company. There is not a single author in the world that isn't disliked by somebody.
So keep doing your thing, working hard, being professional, and writing for yourself, not everyone else.
