Struggling with secret habit

NOTE I made this anonymus acount so nobody knows who i am

Assalamu alaykum. I'm a young man who stayed clear of this for my entire life. About 1.5 years ago, I slipped during a weak moment. It wasn't intentional at first, but then I started making poor choices online that led me to sin.

it wasn't corn but gave the me the same effect. Because my brain was never exposed it gets triggered from anything. Since school started, things got harder. Seeing people around me triggers cravings I didn't get 1.5 years ago.

When I'm not exposed to images or social media, the urges don't hit me hard. The problem is resisting temptation online and around attractive people. I want to quit and go back to how I was before. I had gone one week but then i went on the trigger again, without the visuals i never felt like doing it

Has anyone dealt with this? What worked for you?

JazakAllah khair.
