Another unexpected and delightful result of an intervention is family relief and cohesion. Sometimes just the process of coming together and talking openly is a major force in family healing. It dismembers the addiction in the family. It lets in the sunshine. It destroys control and isolation that addiction demands.
Families always improve even if the addict refuses help.
I call that success. Doing an intervention has yet another huge benefit for family members. It reduces guilt. A family knows that they have now done everything possible to intercede. They have said it all.
