I have heard multiple times that one of the keys to fighting addiction or going through any traumatic situation is to turn to your "Higher Power." They suggest this no matter what religion you belong to.
I found the following Link on LDS.org. It speaks about the atonement of Jesus Christ and how we can be cleansed through him. Through the atonement we can be freed from addiction.
I personally do not know how I would get through the trials in my life without my Heavenly Father and my Savior, Jesus Christ. I hope that, no matter what religion you are, you can find hope and help.
