Could well be Dawn. The reiki master who did a session with me over the phone, said that he's been so ill with electrosensitivity that he'd get burns on his skin, and sometimes just turning the lights on was too overstimulating.

Apparently in Sweden, ES is a recognised illness and you can claim it as a legitimate disability. They then subsidise you in protecting yourself, e.g. with paint that is supposed to shield the walls of your house.

Have you been away from your house, and the mast, long enough to get an idea of whether it's the mast that's causing you to feel so poorly?
