Researchers have estimated that 25-35% of children in the United States have Learning Disabilities. At least 5% have Attention Deficit Disorders. All too many times during the course of their academic careers these children are labeled by teachers (or parents) as being "lazy," or "stupid." Remarks of this type are typically interpreted by the child as, "You're no good," and the self-esteem levels drop.
At least 50% of children will experience the divorce of their parents prior to turning 18 years old. Most children, for whatever reasons too complicated to go into here, will tend to place at least a portion of the blame for the parent's divorce on themselves. Since the parents are typically placed on a pedestal in the eyes of the child, the blame for the divorce cannot be placed on the parents and must be placed elsewhere, most commonly on themselves. This also significantly impacts children's self-esteem levels.
