How do I fix it all

I'm 15(m), 6,0, want to debate, lower-middle class, and a bum for the last few years with no ecs, addicted to porn and social media, and I can't bring myself to do work. want to stop fapping and looking at porn, I want to manage my time and work on SAT work. I've tried banned social media, but I just end up having a bunch of extra time on my hands because I can never bring myself to work. How do I fix this? (Trying to fix my schedule so I go to sleep from 7:30 PM - 4:30 AM). Do I try scheduling my day out so I want to do work? I heard that you're a different person every time you wake up, so how do I stay consistently working, and doing these things? I feel like one component is I just obsess and I can't get out of my head the urge to be cared for by a girl. How do I resolve this too

(Just in case, I want to do better in school, go to gym, study for debate, eat healthy, yk these types of things)
