If you trace the life path backwards of anyone struggling with addiction you will eventually uncover some degree of emotional trauma. As you will hear in Lamar’s case, he first faced his own trauma at the young age of 12.
If an individual is not taught the appropriate coping strategies they need to heal from their pains they will find their own way of handling their emotions. If there is a genetic predisposition towards addiction/alcoholism in their family and they are chemically coping, sooner or later a switch is flipped within and the nights of being “the man” at the bar turn into habits that seem irreversible. His teammates and friends may have partied just as hard as Lamar on wild celebratory weekends, but if they don’t have the propensity for addiction they will never a problem shutting things down. The disease of addiction wasn’t floating through their system waiting to pounce and suck the life right out of them, like it did to Lamar.
