Folks helped them when they were unpublished, and it's likely they'll help you. And pros are people, too, who occasionally are in bad moods, or even ill. I still hear stories about a certain author who was accused of 'hiding from her fans' at a convention some years ago. The woman was sick and actually spending much of the convention being miserable in her room. The story still makes the rounds, though.
Writing is the work of love, but also of craft.
I only recently left a bulletin board where one person insisted that revising her work would ruin it. Other folks have said that if a reader doesn't understand what they were trying to do, it's the reader's problem. If you want to be a writer, you must learn how to communicate what you want to say so that your reader understands. You must be willing to revise. Besides understanding, you also need your reader to be interested, and writing interesting description and dialogue ain't so easy.
