Dealing seriously with my sin

My brothers, I wanted your input on here as I'm someone intensely involved in a battle against PMO that started about a year ago and then became cold turkey in mid-August.
I don't want to overreact by trying to destroy every little enjoyable thing in my life like it's all sin but I've felt-since August-that I need to stop watching t.v. as well. Not all tv maybe but modern tv today and most tv that seems to have a lot of sensuality in it and actresses whose make-up, dress and behavior seem so indistinguishable from a lot of the things I lusted after. I seem to connect the two without even trying. Whether it's a pretty news anchor or cheerleader or lawyer on tv my brain sometimes goes the wrong direction with it. I confess during my addiction I objectified almost anything as if it were a challenge or a game and now that I'm out of it I still FIGHT ALL THE TIME NOT TO THINK THAT WAY.
I don't think I've truly repented of this sin. I say this after spending four months in a recovery center for drug addicts telling everyone I was there because of porn. I think A LOT of men are deceived on what it means to truly repent judging by my study of the Word. I think the heart is wickedly deceitful and I don't want to bully my brain around into thinking a certain way I want this to be a genuine conversion. Mature Christians, am I thinking rightly about this? Thank you and God bless.

 

Thank you for replying Tao but I reached the conclusion earlier that day that I can't trust men to answer these things for me, only to check my thinking. I think I just have to believe what's written in the Bible.
