Anonymous, make yourself extremely cold in the night, or extremely hot. Although this is seriously unhealthy and you can really harm yourself. But it doesn't have to be a fever right? You could just make yourself ill. I once stuck my fingers down my throat and made myself sick, then showed my mom so she let me have a day off. Another time I told my mom, she said she'd let me have the day off if I went to the doctors. So I knew I had to really make myself sick. Holding your breathe for as long as possible, breathing a little again, holding it again, will make you dizzy. Drink a HELL of a lot of water and spin around in circles. It makes you feel soooo ill :') And I fooled my doctor by doing that.
