Now, over eating is something we do when we really feel like disappearing, but don't have either the will or power to commit suicide. It stems from anxiety, depression and past traumas poorly dealt with. What you can do, in a room, alone, run over your life's traumas, see what can bring a tear to your eyes, and for everything that can bring a tear, you have to really cry like a baby, feel as sad as you can, and cry till there are no more tears.
With a band, and overeating, you can do serious damage to the esophagus, causing tears, that can kill because the bleed severely.
As soon as you treat your life's traumas, you will find it easier to eat smaller quantities and feel better with yourself.
Now, the most important thing, don't hate your body. It is only the result of past actions and thoughts. Now that you are on a better path, just look ahead, feel thinner, and think that you ARE thinner, and that will empower you to reach your goals.
