Sorry you are feeling sick to your stomach. What about liquids?
When I read your post about how you have to deal with bullies, a light went off in my head. That could be the cause of your nausea. Maybe a therapist that specializes in bullying could get to the root of the problem.
Here are some articles that discuss similar question.

Some people in your situation go to a medical doctor to find out if there are any physical reasons for the nausea.
What about dramamine or other anti nausea meds? Ask your doc.
