Hi, ggky59, and welcome to Psych Central! As you know, the worst case scenario would be that she would force you out or outright fire you. But life would go on if she let you go, would it not?

One techique I use is deal with anxiety is to breathe air in and then slowly let it out. Also, you can visualize something pleasurable and comforting. Ignore her as much as you can without making things worse. Bring things physically comforting in your pocketbook such as a smooth piece of marble you can rub, a soft piece of cloth, one of those little pamphlets with the smell of a new perfume you like, whatever. Plan things to look forward to in your life and try to see your job as less an "outstanding" part.

What else, folks?

I do hope things will help you relax more soon.
