Originally published in 1939, the “Big Book” has led many to insights into the reasons and behaviors that eventually lead to addiction. Pushing further, it also details how an addicted person struggles with negative thoughts and emotions that come from their addictions. Codependency happens when another person’s problem becomes your own. You lose sight of your own life as you take more and more responsibility for someone else’s. Unfortunately, this happens a lot with people who take care of their addicted family members.
