An intervention is a planned conversation, not an ambush. The version you have seen on TV, where everyone corners a person and lists their failures, is not the model that works. A good intervention is structured and calm. You gather the people who matter to your loved one, you speak honestly about what you have seen, and you ask them to accept help. The help is already arranged before the conversation starts. That is the point. One goal, one clear next step, and a bed waiting.
