I agree with Rcat. I just want to add..

This sounds like a very bad boss. Do not internalize that and let him control you. Now, I realize that helps the anxiety very little...but once you calm down just remember -- You deserve respect. I know all too well being the "Good boss" who read all the leadership books, and dealing with the "Bad Bosses" that were mine. I don't get it...But people still continue to do it.
