You have to do the work. Abstinence from porn is the answer. It is the only way. If you want to heal, you have to leave porn behind 100%...no peeking.
In years past, I tried to quit many times for various reasons, birthdays, guilt, new girlfriend, getting married, having kids, etc. It never worked, but back then I had no idea about pied or brain changes due to porn addiction. I thought it was just something I liked, but later felt bad about. Regardless, the white knuckled approach never worked for me and it usually doesn't work for others.
So my advice....
1. Go to yourbrainonporn.com. Read every link about porn addiction and pied. Read every success story. Read every reboot account. Watch every video. Realizing what porn addiction is is critical knowledge. You must know thy enemy before you can hope to defeat it.
2. Start a journal here (which you have) and post on it often, daily or more at first if necessary. It helps to get your thoughts and feelings on paper, so to speak. Others who are going through or have already gone through the same process will offer advice and encouragement.
3. Participate in other people's journals and success stories. It helps to become part of a community of people working together with a common goal.
4. There are other sites as well such as nofap and yourbrainrebalanced.com ...absorb all you can.
5. Find a hobby or interest to take place of the time you spent with porn. In the beginning, this may be tough. All I could think about was not thinking about porn, which in a way was still keeping porn in my head. So, my hobby was learning about the addiction and focusing on success stories who have been healed. Slowly, the anxiety eased and I enjoy other things.
6. Believe in the process. It works. It is beginning to work for me. Life is much better, but I definitely have low times and temptations, but they are easier to deal with.
I am sure you'll get tons of good advice from others. Good luck and stay strong.
