In in a similar situation. I liken it to being wrapped in a fog. Not depressed, not anything...it just..IS. I turn d off the tv today and started playing music, most know DNA of laminating and longing types interspersed with uplifting Renaissance folk dance. I kept staring at my book then bit by bit I was able to focus. Maybe you could give yourself time to just stare at the wall...maybe that's what your mind wants or needs to recharge? Try to go easy on yourself for not having any words right now.
