So let this be a lesson: if your life blows up, don't tell anyone. And most of all, DON'T tell the person who is supposed to have your professional back why you're struggling to complete things. (I say this sarcastically).
Wow. Screw that. Seriously. You're the second person I know who has a story like that - agents "breaking up" or being jerks over totally personal matters. (The other story was, believe it or not, over the author's weight.)
Which makes me so thankful, once again, for my agent. He knows what happened with the baby, and over the past few months we've gone back and forth over an outline for my second book. I was so very aware that he had multiple opportunities to say, "Look, maybe you're too emotional/distraught/whatever to do this right now" or "I think you want the book like this because this happened to you." But he never did. He kept it on a completely professional level and he allowed me to do that too. It was actually a real help to me to have something to work on that was completely "other," where I could just "do my job," so to speak, and not be all emotional. I'm glad he respected that. Hm. Time to send him another note.
