To overcome a spending addiction, the person needs to first realize they have a problem. The person needs to confide their addiction to friends and family to build a support system. Someone addicted to shopping might seek the help of a therapist or join a support group.
The person needs to catalog their recent spending sprees and determine if there was a trigger that led to it. Once the person establishes a pattern of triggers, they need to develop new tools for dealing with the stress that previously led to unnecessary shopping.
A person with a spending addiction needs to devise a reasonable budget that allows for some discretionary spending. A spending addiction may have placed the person in debt, and a plan needs to be created to pay it off.
