Kate, you may want to have some genetic testing to see if you have mutations in any of the genes related to methylation. That's the process that breaks things down in our bodies for clearing out or recycling. I have a COMT mutation which makes it difficult to break down stress hormones, toxins, etc. I wonder if EMF exposure creates more cellular waste that needs to be broken down and cleared. My gut feeling is that it does, and that could be an explanation for the very real effects. If you're not able to clear stuff out quicky, it buìlds up and causes symptoms. For the mutation I have, supplementing with a high quality B vitamin complex helps with methylation. There are other nutrients that are also needed for the methylation process. I'll post a link on this subject in case you want to read about it. When my COMT gene was tested, the doctor also ordered testing for nutrient deficiencies. I was very deficient in B vitamins as well as C and some others needed for methylation. Since I've been supplementing, my health has improved, and it even eliminates my post-menopausal hot flashes. Hope this info will help.
Oh, and, I read there is a community in Snowflake, Arizona for people with sensitivities.
