In families where alcohol are being abused, behavior is frequently unpredictable and communication is unclear. Family life is characterized by chaos and unpredictability. Behavior can range from loving to withdrawn to crazy. Structure and rules may be either nonexistent or inconsistent. Children, who may not understand that their parent’s behavior and mood is determined by the amount of alcohol in their bloodstream, can feel confused and insecure. They love their parents and worry about them, and yet feel angry and hurt that their parents do not love them enough to stop using.
