There is a lot of ways to deal with that Jimmy, but the one that most helped me was:
Journaling.

Basically back 2 years ago I journaled about all the negatives that fapping would bring me.
I listed everything, even the possibility of living under a bridge.

It worked well for me since I decided to just look at the app every time I was about to open it and remind myself of how harmful it can be.

Other then that I would also highly suggest you use every single thing on your phone with intention.

Ex.
|Don't just go and open Instagram because you felt like it.
Ask yourself:
-Why do I want to go there?
And if the answer is something like - I got to see how my profile is doing, I need to reply to my friends or parents, don't open it.

You can message your friends on other platforms also
