Nobody else can decide if we are an addict (though the legal system can help make that decision).

The admission of being an addict is essential for recovery to work in our lives. Step One: "We admitted we were powerless over our addiction and that our lives had become unmanageable." It is only through that admission that lays the foundation for the rest of recovery that we can find a different way of life.
