trying to quit

New here trying to quit porn for good, it's taken to much of my time and energy for something that isn't even worth it, would like to cut it out of my life for good. Advice would be appreciated thank you in advance.

It's my first day trying to stop this habit, I've already tried it a lot of times but I always relapse. I've got to the point where I became a Sex offender and ruined my high school life and after that point I've been feeling like a fucking monster.
