Did you have a lot of anxiety when you first started the query process? Any advice on fighting through?

Um. YES. So much anxiety. I cooked like twenty bread puddings. My best advice is to 

1. Read the rejection letters other authors you admire have received. 

2. START WORKING ON SOMETHING NEW. 

3. Try to remember that rejections are often not any kind of reflection on the quality of your work. So much of it is timing, the market, what the person you’re querying last signed or even last read. It’s impossible not to take it personally or to let it get to you, but we all went through it. 

fwiw, I’m rooting for you.
