Been addicted for over a decade

I've been addicted to porn and masterbation for over a decade now. I've watched all kinds of videos, pictures, and even stories of various things. I've been *** every day, sometimes more than once a day. It's been interrupting my life and my realationship. My reward system in my brain is fried, I have desetisation and damage to my groin. I've given myself PIED. I don't have a support system besides my wife. She knows and is encouraging me to seek help besides myself, white-knuckling this addiction. I've been clean for almost a week, but the urges are daily. Any kind of help would be greatly appreciated.
