I think in many cases there is a negative reinforcing aspect to anxiety that needs to be addressed. For example, anxiety can trigger certain physical symptoms like sweating excessively, tension leading to e.g. reduced loudness and loss of voice, clumsiness. This can spiral down and eventually the anxiety can be almost entirely about those physical aspects.

This is just a different way of looking at it. What you do by addressing what you call dread is basically putting a halt to this feedback loop.
