I struggle with my addiction

I have had a addiction since I was about 11 years old and that addiction is porn. I am only 14 years old now but i know this can be stopped before its to late. My mom does know i used to have this problem but she dosent know it has come up again. I believe in total holliness but i know this isnt holy. Iv'e prayed and called out for Gods help but it dosent seem like he hears me. What can I do.
What Kirk did you do when you were in the situation
