I'm on week 5 SS and haven't cheated once. Every weekend my mood plummets but today it has been rock bottom. I've been crying for no reason and I feel so dead inside. I'm also physically and mentally exhausted; I slept for 5 hours when I came in form work tonight and I'm still tired. I have not lost any weight since Saturday and the scales normally go down every few days. What's really worrying me is that on other diets my weight loss always stops altogether and the diet stops working- it's as though my body has got used to diet. I'm terrified this happens on CD. But also I just feel so down, people at work were telling me today that they are really worried about me, that I've lost my sparkle. I don't know if I can continue. Please help! x
