Having a drug addiction is hard enough. So is having a mental illness such as schizophrenia, depression, or an anxiety disorder. Imagine having them both. You'll find out what that's like in Dual Diagnosis: Drug Addiction and Mental Illness. Many people suffer from both an addiction to a drug and another mental illness, making everyday life almost impossible. Dual Diagnosis explores ways to deal with dangerous addictions on top of mental illness. The book covers what addictions and mental illnesses are, diagnosis, and multiple treatment options. You'll also read inspirational stories about people who have suffered with—and overcome-dual diagnosis.
