Your identity is much bigger than about being a writer, and writing is much more than sitting in front of a keyboard.
Live well, and that will help you write well.
Writer's block is a signal that you need to get up, get out and give your life a stretch. Enjoy who you are in Jesus and let Him teach you something new.
You have so much going for you in the love of God — what if you never got back to writing?
When you can let it go, then it has become your servant, not your master.
