My weight

At the moment im a size 12 (u.s size 8) But i'd really like to be a 6-8 (u.s size 2-4) . I weigh around 11 stone, and i think i'll need to lose about 2-3 stone to achieve this. I've struggled with bulimia and am still getting over it. So i don't want to go all eating disorder. But i do want to lose weight fast. Within the next 2 months i want to lose 2 stone. By any means necessary. I'm going to attempt a twenty day fresh juice/water fast. I'm going to start it tommorow. I'll go buy some nice fresh juices from wherever. I'm quite excited, and i'm going to have a nice feist tonight! :) I love juice, so i hope i can stick to it. I tried the master cleanse, but it was impossible because the mixture was so vile!! So this should be good, i hope i can do it. I need to do it. I'm so insecure about my weight. I see all these amazing clothes which i feel i just can't wear, because of my huge bum and thighs, and my jelly belly and love handles. I'm just so chunky and big. I'm quite tallish, but i seem to be shrinking. I was 5 ft 7, now i'm 5 ft 6. And sometimes you shrink when you lose weight, so maybe i'll be 5 ft by december. Or maybe not. I also have a really fat face. I'm close to having a double chin,and have flabby cheeks. I do have nice high apple cheeks and cheekbones, but they are covered in flab. I need to lose that so my face looks nice, rather than a blob. Then my features will look nicer. I have quite nice blue eyes, a button nose and quite big, full lips. But my fatness and my spots make those features seem in the background rather than stand out like i'd want them too. I need to do this!! Big time!
