Hi DP,
Have you tried asking your doctor for Omeprazole (or whatever the equivalent is where you are?) for the nausea?
I had a boss five years ago who left me so stressed, that I was throwing up every morning. Omeprazole helped with the nausea, and when I left that job, I decreased dosage and then came off of it. But it did help while I was on it.
I'm sorry you're going through this.
