Addiction is a complex disease that affects all aspects of your life, whether you realize it or not. You can’t treat addiction without also treating its other effects or causes. Depression, anxiety, and post-traumatic stress disorder (PTSD) are common examples. It’s usually called a dual diagnosis, co-occurring disorders, or comorbidity. They all mean the same thing, and they’re all extremely common among addicts.
Unfortunately, the symptoms of co-occurring disorders often make your addiction worse. For example, you drink because you’re depressed, and you’re depressed because you drink. In other cases, drugs or alcohol may be the “medicine” that makes you feel more at ease or confident. For lasting results, these problems must be treated at the same time.
