Weight loss and children: weight and depression
Frequently, overweight children grow into angry adults who turn that anger inward. There is another word for anger turned inward - depression. Consequently, there's a high probability that you are angry and depressed about being overweight. You are also perhaps angry at the individual or individuals who made you feel bad about being overweight. It's even possible that you keep the weight on and refuse to flip as a way of getting back at that individual. Losing weight would constitute a "change." Yes, either consciously or subconsciously, you continue to hold on to the weight as a way of striking back at that individual, or you use it to avoid dealing with other issues in your life, such as personal relationships or career goals.
Psychiatrists have long noted these behavior patterns among overweight patients. Right now, if you are holding on to your anger, the only person you are hurting is you. The individuals responsible for this anger may be gone, or elderly, or most likely don't even remember what they said to you, yet you are allowing their mental picture of you to prevail. This emotional anger is preventing you from believing that you can succeed at weight loss. It is their image of you that is still defining you today. You need to cast this aside as you approach losing weight.
