Like the psychoanalysts, the cognitivists would remind you that anger is a deeply rooted defense mechanism that protects us from a variety of situations from which rescue is perceived to be necessary; its power and energy aiding in both emotional and physical survival. So that can be a good thing, but the downside is when anger becomes horribly mismanaged and taken beyond the boundaries of its biological and psychological purpose. It then becomes incredibly dangerous.
Well, that's a wrap for part one. Hopefully, I provided a nice definitive foundation as we look to part two, and our discussion of how anger directly impacts panic and anxiety.
