“My dad drinks too much and everyone pretends it's fine”

What could be going on

Substance addiction: Fits if drinking continues despite harm, with loss of control.

Whole team sees the problem, nobody says it: Check whether everyone knows and no one names it.

Codependency: Could be family members organising life around managing his drinking.

Family roles (golden child, scapegoat, lost child, mascot): Check whether children took roles: hero, lost child, joker, scapegoat.

Adverse childhood experiences (ACEs): Growing up with parental addiction counts as childhood adversity; check its effects on you.
