Help me plz

Before I begin, I just want to say that Ive been going through this for a while and please don’t think I’m gross or anything.

I’ve been addicted to pornography since like 4th grade. I can’t stop looking at it. I want to be free from it forever. I know it’s affecting my relationships badly.

Also, I’ve been masturbating as a result of the porn. In my religion, masturbating is a sin before you’re married (Mormon). I know the only way to get myself away from this is to stop looking at porn but I can’t.

I can’t talk to my parents or anyone about this. I’m 13. I know my parents would support me and help me but I can’t let them down. I need a way to get through this by my self. Any tips or advice would be greatly appreciated, but please don’t tell me to talk to someone.
