It is unlikely that your doctors will report you for prescription fraud. They're just going to stop prescribing for you.
You need to see a treatment specialist who treats both addiction and chronic pain. There are treatment centers that specialize in this.
And your husband knows. He may not be ready to do something about it, but he knows. Your kids know, too. So the only question is would you rather be their recovering wife/mother who realized her problem and handled it, or would you rather be their practicing addict wife/mother who can't get her stuff together?
