Hi, I m 17 I have a few things worrying me. I have to rely on laxatives to go to the toilet. I ve put on about 6kg in the past month. I can t sleep, I ve lost my appetite, I have to force myself to eat once a day so my stomachs not empty. I get hot flushes throughout the day, I get dizzy and a bad headache, my head gets really hot and I have to sit or lay down to feel better.
