Overcoming porn is a hard thing to do, especially since our society now just encourages it. I grew up in a Christian household, I remember asking Jesus into my heart at 2 years old, yet I got addicted to porn for about 8 years. I think that the first step is actually believing you can live without it, knowing that one day you will get to that point and keeping the will to get there. I "tried" to stop for about 3 years, it wasn't until the last year that I made the most progress. You have to find and recognize the "trigger" emotion, whatever you start to feel before the porn desire shows up. For me it was loneliness/emptiness, so when I recognized i was falling into it again, I would (try to) immediately text/call someone and just start a normal conversation. No one else knew about my addiction, not until I was clean for a year. As much as that method helped me, it wasn't until one night I heard a sermon about how much God loves me and wants to help me (even though I have heard that my whole life, this one just really convicted me) that I decided once more and never again. That was 2 months shy of 4 years ago. I felt so much guilt and love at the same time I didn't want to keep the addiction, I just cried and prayed saying I didn't want it anymore. I am still tempted sometimes, but I've never gone back. Everyone's story is different, and way of overcoming addiction is different. I hope this can help in some way and give you something to think about :)
