This is a great video by the LDS Church showing the slippery slope of addiction. I think the message can still be applied to variety of struggles and addictions- not just pornography. What demons are you fighting and what's been helpful for you?
When we face such temptations in our time, we must declare, as young Nephi did in his, “[I will] give place no more for the enemy of my soul." I promise you that the light of His everlasting gospel can and will again shine brightly where you feared life had gone hopelessly, helplessly dark.
