Hi cat, sorry it has taken a while to get back to you. It seems that your attitude towards your physical form and food have a very tangible basis, and not a good one. Your sister was very mean, as sisters often are (without meaning to be), and unfortunately their painful words can, like all things we hear repeatedly when we are children, stay with us. So your sister's cruel words have stayed with you, and when you started gaining weight (even though you were far from fat), you felt fat. At least, that's how it sounds to me. Does that sound like that might be what's going on?
