Dude, chill out! You're being way too hard on yourself. Love yourself more. Take a break, do some side projects, like that book, and just take it easy. The problem is, creators like you want to perform, and if you can't because of your expectations and what others think, you feel like a failure.
Stop think about whether this is something you can control and focus on that and ingnore the stuff you can't control.
But don't quit just yet .
Cuase your story's matter 😉😇
