Many rehabilitation programs in Jewett, Illinois address people with co-occurring mental and substance abuse disorders. A client who struggles with a mental disorder(s) and substance abuse needs to work through both issues simultaneously. Failing to tackle the client's psychological disorder(s) during their drug rehabilitation will leave them susceptible to relapse once they leave treatment. Troubles with mood disorders, anxiety disorders and other psychiatric disorders (schizophrenia, personality disorders, etc.) will surface once back in their day to day life. If the person does not have a grip on how to deal with their mental disorder they will likely fall back into their old ways of abusing drugs or alcohol as a means of coping and self-medicating.
