Welcome Gabriel, it’s very nice to meet you 
There are many people struggling with porn and there’s a good number of people here working on that. If you search “porn”, “PMO”, “masturbation”, and other similar terms in the search box you’ll find many threads.
This thread is one that has been fairly active over the last year or so:
PMO - Porn, Masturbation, Recovery
For me I found my porn use was a habit that got entrenched largely because I’d neglected my whole self, my sense of achievement, my sense of connection and healthy intimacy and healthy risk-taking and achievement - all those patterns were underdeveloped in me and the porn use was keeping me distracted from the work I really needed to be doing (which was about building a foundation of constructive behaviours; as that foundation is being built I am finding more and more the idea of turning to porn loses its “appeal”).
Take it one day at a time. Reach out for help. For me I joined a sex addiction recovery clinic in my city, and that has helped me a great deal. Don’t give up - the key is determination and action.
