Hi Keeway,
It is important that you take care of yourself and develop strategies or obtain the right treatment for you in order to deal better with the anxiety. If that means you need some more time off work then that is what you need to consider. Do what is best for you and what you feel most comfortable with. However, keep the lines of communication open between yourself and your bosses. How did they react when you discussed your anxiety with them?
As Genejockey says, perhaps working even a few hours a week may help you by distracting you. But it sounds like you are not ready to go back. Please do work through the program and post often as this will also help you to feel more at ease.
