I really need some answers, please help me

I just joined Reddit so I could ask a question on this thread because I really need some answers. I'm 15 years old and I started too become addicted to porn towards the end of my eighth grade year. Before I started masturbating to porn I was getting a lot of attention from the girls at my school and when I started jacking off too porn this all began to stop. I was also with a girl that I really loved, which uwas the first time in my life I've ever loved someone that much and I threw it all away because of my addiction. I was also a very exceptional football player throughout middle school but after I became addicted to porn I became much worse in my performance and eventually just didn't care anymore. About a month ago I realized what porn was turning me into and I decided to quit. I stopped masturbating too. I've experienced extreme depression to the point of just not caring about life anymore while I was addicted to pmo and so I stopped. its been a month and three days since I quit and I was very confident the first couple of weeks like I was before I started pmo but now I'm starting to become like I was when I was addicted. I also can't even achieve an erection. Am I going through the flatline? If so, how long will it last? I'm a virgin so will it be longer? Does me being socially awkward and reclusive have to do with this or is it my hormones? Sorry about the length of this I'm just really scared tbh and I really need help.
