Remember to have a little faith. When you die, I believe, God isn't going to ask you what you published. God's going to ask you what you wrote.
Doubt is a storm. We either ride it out, or we change our course. Neither is right or wrong-to stay or go. Twenty years ago, should you have really married X, or Y? This college, or that? A life-changing decision one makes becomes the right decision by the fact of simply having been made.
