Teens - Confessions

Hi, this is tough to even type. I've been struggling with porn for a bit... I have what I thought was a great relationship with Christ but when I first came across a certain porn video online I couldn't look away. Now I'm off to school and moving out and I've done dumb things to myself all relating back to viewing and reading pornographic content... I want to change, I want my relationship with Christ back the way it was, I don't want to feel this shame and not be able to sleep at nights because I feel so guilty and hate myself so much... Does anyone have any advice on how I can beat this?
