No one can force you to do anything. You chose. You always choose. You can choose not to weigh yourself; you can choose to have a dash of milk in your coffee; you can choose to begin that furtive stumble towards the light.
Conversely, you can choose to remain behind. You can choose to cower. You can choose to starve, binge, abuse yourself. It is a compulsion, yes, but it is a compulsion that can be fixed. Patched up. Knitted anew into a healthier form.
