Dysfunctional families are fertile ground for neglect, abuse, secrecy, addiction, or denial. In these family systems, children’s emotional needs go unmet because the parents’ needs take precedence. One or both parents might be suffering from a substance use disorder, personality disorder, or mood disorder.
In other cases, parents are emotionally immature or unavailable—caught up in workaholism, shopaholism, gambling, overeating, adulterous affairs, or other pursuits.
