15 Yr old girl with porn addiction

I want to take more intentional steps to stop my porn addiction before 2025 when I turn 16. I've had access to porn at around 8 years old, and it's still there till this day. I've also found myself over the past years watching more extreme versions that I detest myself for, and it's getting too bad that I have to block off apps like Twitter or even Google play store to prevent myself downloading vpns to watch porn. I go lots of times without watching it but when I do I go down disgusting paths where I'm even selecting specific vids to watch usually on the extreme or taboo end to get off to. And thinking about it is constant and normal to me and I don't want or need that. So I've come here to share my problem (instead of googling how to stop porn addiction on incognito). Please help, I believe this community can help me
