If I may make you a reccomendation, try staying away from all of your technology and such for a short while, and pray to God and read the bible. When I had some problems with pornography, I did this, and it really did help. I was no longer attacked as hard, I was further away from the world now, and it was harder to tempt me. So, use that time to grow in your faith and rebuild your defenses.
I will pray for you though, and if you do want to get free from this, and truly want God's help, you WILL be freed.
