Quick background:
I got married a few months off my mission and then my wife left me two years later. Since that time I've been a wreck. I've been active in the church, never missing a meeting and serving faithfully. I don't live in an area where there are many single adults so I oftentimes feel like the freak divorced guy that is just there but not really part of any group. It's quite depressing to have always been faithful in the church and all of the sudden not feel that you are accepted anymore.
Anyway, my ex-wife was unfaithful, which is the reason why she left. I've been completely destroyed since then. It's been two years and I still haven't gotten over it, the wounds feel as fresh as if it all went down yesterday.
In the last few months I've begun to question the existence of God. How could someone as faithful as me be completely screwed over like this? I know people that have lived sin filled lives, mocking the church, and were able to create successful marriages and repent later on. Why is it that the people being complete idiots with the gospel are able to get this blessing of happiness in marriage while I haven't? I did nothing wrong, my stake pres even had to take me aside to tell me to stop beating myself up because my ex had major issues and it would have happened eventually.
But in the last few months I started to look at pornography. I've noticed that I used it as a way to numb my horrible feelings about life. It hasn't been a daily occurrence. It would happen a few times one week and then not again for a week or two. What I noticed is that every time I felt angry at God or depressed I would turn to pornography to numb the feelings.
I've decided that it's time to stop that behavior. My question is this: Is that something I need to confess to the bishop? It didn't involve anyone else but myself. It's following the classic patterns of addiction, which scared me and caused me to look more seriously at my behavior. But if I don't need any addiction recovery help, is it still necessary to talk to the bishop about it? It was my understanding that with porn the reason you talked to your bishop was to get help, not necessarily to confess a serious sin.
Thanks for the help.
