It happens to all writers. Admit it and face your fear. That's what I've decided to do. Until we face our fears we cannot conquer them. I hate to break it to those of you still on the agent hunt, but it doesn't stop once you get an agent. For a while it does, but then comes the moment when you hand your manuscript over and they submit it to publishing house editors. The wait and the stress begins again. Doubt creeps around every corner, within every empty in box, and every empty voicemail. It can grow like a great demon with every passing week if you allow it to. It can consume you, and it will if you let it.
A few of my friends who are waiting on submissions are battling the doubt demon right now. Heck, I battle it myself every day my manuscript is out there being considered by publishing houses. I have bad days, but they pass because I know how combat them. First, I know that what I sent off was as polished as it could possibly be and is worthy. You of all people must believe in your work and support it 100% or else no one else will. That doesn't mean doubt won't creep up on you, some days, it will. What it means is that you will be able to face doubt and force it to back down.
One way to do this is to keep busy. Writing another book is a fantastic way to take your mind off the horrible wait. Networking and building your writer's platform is another great (and necessary) use of your time. In seeking other writers and readers you will also find the support you so badly need at a time like this. With that in mind I'd like to thank every one in my support net, my followers and friends here, on Twitter, and on Facebook. You keep my writing hand strong so I can not only write that next book, but fight off the doubt demon as well.
