The gambler may also have borrowed money from other family members with no way to pay it back. He or she may have sold family possessions or run up huge debts on joint credit cards. When faced with the consequences of their actions, a gambler can suffer a crushing drop in self-esteem. This is one reason why there is a high rate of suicide among problem gamblers. CBT is a form of psychotherapy that emphasizes the role of thinking in how we feel and in what we do.
