Many individuals in Sullivan, IN. who find their way to drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who struggle with mental health issues in Sullivan also take part in substance abuse at some point in their lives. These dual diagnosis clients frequently turn to alcohol or drugs to self medicate as a way to relieve the symptoms of an underlying psychological issue. Some addicted individuals aren't even diagnosed with a disorder, and only when they begin to receive treatment at a drug rehabilitation center is this sort of issue brought to light. This in itself can sometimes help resolve addiction issues and put the individual in a position to receive treatment for both conditions so that they have a good chance of remaining abstinent and psychologically stable in the future.
