Struggling

Boys im ngl ive been doing really bad. I started this thing and i didnt watch porn for like I think it was 12-13 days. And in that time I masturbated once. Since then I started masturbating and it led to porn so then I started resetting the time for either cause I wanted to stop both but now I can’t seem to get to even two days without relapsing what do I do. I started so strong do u have any tips
