Feeling lost

I don’t know what is wrong. Feeling so helpless and lost. I used to be able to go weeks without watching porn and masturbating. I even almost hit a month one time. Just kept relapsing. I would then be able to go for two weeks at a time and then relapse and time in between just keeps getting shorter now. Now I hit 8 days and saw some instagram ads that did everything to taunt me. I kept trying to talk myself away from it. Kept trying to think of anything else but it didn’t work. I walked right upstairs and relapsed. I relapsed while my wife was at work. I hate this, man. It’s so aggravating and I don’t know why I can’t go as long anymore. Pray for me. I want to fight this. I want to win and overcome the battle
