8 years of pain

I discovered the world of masturbation when I was in third grade and the world of pornography in ninth grade. I just graduated high school. I'm 18 years old and has had this problem for 8 years now. I'm also a woman and I thought I was the only one with this problem. Now that I ow that I am not and have talked to a few friends about it, I feel that this is my time to get better. Please pray that God will give me the strength I need and the determination I currently lack.
