If you are struggling with a friend or a loved one who has a substance abuse problem or addiction to a behavior, you know a sad truth. They are liars - They lie about their problem and almost everything else. My partner left me because of the lying more so than the drinking. Addiction is called the disease of deception for many reasons.
One of the reasons that we become liars in our addicted states is because our brain could never accept the truth of what we are doing to ourselves or others. We must lie in order for our behavior to become acceptable to us. We must lie so that we can live with the intolerable parts of us.
The first step in recovery is admitting we have a problem. The first action required is to start telling the truth.
