Are your thoughts about your eating and your weight unsayable...even to yourself?
It's not so much a question of being waif-thin, looking like a model. It's a question of what you are doing to yourself, whether you are hurting your life by being overweight. Only you can know.
You can be 5'4", 150 lbs, and feel free as a bird. But you can have 20 gained pounds on you that weigh you down like lead.
It's not in the number, it's in your heart and soul. If you are eating away your fears, your anxieties, your passions, your ambitions, if you are embarrassed and helpless in the face of the problem - these are the real issues.
What do you tell yourself about your weight problem? Can you tell the truth? Can you say the unsayable?
