Brother,
God loves you more than you could possibly ever understand and desires to heal you of what you have done to yourself. Do not resist His chastisements for sin when they come, because they are always given out of love to heal you. I’ll share with you my personal story and perhaps it will give you some measure of hope for healing.
I am a 32 year old male, Catholic from childhood, and married for 12 years to the only person I ever even dated, with two beautiful daughters, ages 10 and 8. Sine I was approximately 12, I have struggled with compulsory porn use. I confessed it to my wife, and would repeatedly fail but most of the time was able to conceal it for many years. I more or less gave up on being able to stop due to many years of failure.
I left the Church and started going to a baptist church, because I lost connection to my own faith that I never really understood. Part of the motivation to leave was because you did not need to confess ones sins there, and I thought maybe I would be more at peace with my porn problem. I was obviously wrong about this improving things.

I believe with my whole heart, God permitted me to continue doing what I wanted so that it’s horrible consequences would help me back to Him. Take down the pictures, but don’t despair. I promise you, it is totally possible to live without it and find peace. Trust Him to help you fix it, pray every day. The Liturgy of the Hours is a great way to bring your mind back to God throughout the day. I’ll pray for you. Hope this helps.
