Getting rid of an addiction is a process, a painful one. When you get used to a certain fixation and you lived life consuming it, hard is not enough to describe when its time to let it go. Building up anger is necessary. Doing it cold turkey making all efforts to pay no mind is beneficial. Did I mention cold when I say cold turkey? I mean, one way or another, you need to see that addiction as an enemy. Until you're strong enough to move on to the next phase...withdrawal is hell.
