I can relate, about three years ago I had gone several months and was doing well (From about June or July to March) and one day I slipped up and was browsing on my laptop when I caught a virus, which then spread more viruses, that took over the computer, leaving the computer virtually unusable. My only option was to call my dad, who works with the building and cleanup of computers daily, and explain what I had done. While we had tried to clean the system of its viruses, it never fully recovered, and last I knew, it still sits dead in our basement.
Sometimes God works in ways that we absolutely would not expect, and actually come to dread. That is the one thing I remember from that day, when that computer caught the first virus and then my antivirus not being able to catch up with the attack, I knew I'd been caught red-handed.
I pray that this can truly be an end for you, brother. My suggestion would be to try to explain to your parents what happened, and then once they're calmer, explain to them why it is a good thing. It is one of the most painful things I've done, coming out to my seeming addiction to lust. But in the end, it has set me free, and just by being open and admitting my faults, made people want to help me, which I was certainly not expecting! Three and a half years later later, I am one day farther from the pit. Still struggling, crawling some days, but walking away.
God bless.
