please please do not create this negative body image of yourself. Everybody has bits about them that aren't 'perfect'. I thought I was over weight at your age and I started on slimfast, one million diets, an eating disorder, a years worth of therapy and a conciderable number of stone later, I am very overweight because I have screwed with my body so much. I would kill to go back and act on what I know now. Don't get hung up on it, it doesn't matter. Focus on the bits of you you like and emphasis these bits.
