I haven't read either. Depression is different from anxiety. So, you might gain further insight as to what they are. I have a neurological illness that was diagnosed before either depression or anxiety, so I am going to discount the notion that either or are both only due to cognitive distortion. There's a physiological component with some patients. Still worthwhile to study as you address your own wellness. There's also a Books, Movies, TV forum, if ever you'd like to leave a review or start a discussion.
