You can change the way feel about it, you can change the way they act upon it.

An addiction is just a thinking method or a belief method. Certain beliefs lead to feelings that lead to behaviors, and they are often irrational, illogical, excessive, exaggerated beliefs.

A cognitive behavioral therapist will focus primarily on the thinking component, will intervene first, talk about the thinking that leads to these feelings or behaviors.
