Have you thought about cleansing your body.....
From first hand experience...... (bulemia& anorexia) I know that eating disorders as well as Depression can be caused ny both chemical and heavy metal imbalances in the body.....
You can be happy, and free from you pain ... you just need to be willing to do some stuff to help yourself....
