I can't emphasize enough how important it is to get to the core issues involved with addiction. You can think of addiction like this--most addictions are a means to self-medicating a deeper problem. If we are holding pain inside, we don't like that. So people turn to alcohol, video games, sex, drugs, work, and other things to avoid feeling the pain. By turning towards the pain, you can begin to investigate it and get to the core issue, which could be a trauma, the experience of being unwanted by your parents, or something else. Once you heal that core issue, the need for addiction can dissolve.
