It's like a deep jump. If you had to jump for your life, you'd get your chest down, your hips back, and your knees out. Try that. Just jump. Don't think about it. Now, when you squat, do the same thing. In other words, your hips are too far forward on the way down. Get them back and bend over.
Your upper back is rounded as well. We don't need flared elbows. Check out Delgadillo's article on elbow pain in the squat and look at the pictures.
Are you eating right now? You should probably be eating. Good luck!
