I hope this post will help ?
Firstly, don't beat yourself up. High speed Internet has brought with it a whole load of problems. Mainstream media, social media ... and the porn industry are all continuously seeking for our attention, so that they can prey on our vulnerabilities, until we succumb to their persistence. A click on a rogue link will be for their gain, regardless of the personal cost to us.
We have all fallen for their scrupulous methods.
Secondly, and most importantly, you're in the right place. There is a lot of information on here to help overcome the addiction.
I joined this forum / support group sometime ago, way back, but didn't participate in any discussions, thinking instead that I could overcome the issues on my own, and all my problems would go away. I soon realised that I couldn't, but gained reassurance that I wasn't the only one struggling.
I definitely recommend starting a journal. There is a post at the top of each board that gives guidance.
It helped me to do some "soul searching" to understand how I got into the mess I did, and what were my triggers. I was then able to "plan" to avoid being in the situation when I was most vulnerable.
I did "fail" quite a few times. It's hard at first, and I had to keep reminding myself why I had to overcome porn addiction.
I wish that I had found out about this forum / support group earlier, and had the courage to face up to the situation I was in sooner.
Good Luck. Be strong. Be positive... And don't give in.
