Fighting against my demons, ego and guilt

Hello guys, i'm 21 yo and just broke up with my GF. For many reasons i had to make this choice of breaking up. Mainly because i never liked her, just asked her because i wanted to prome to me that i deserved to me loved. But that post is not about her or my ex relationship. I just wanna share my goals and what i've been doing.
As the titles sugests, i have my own demons. I always had been the "good looking fat guy that if gets skinnier, would be handsome" my entire life. I suffered bullying since i was a child, got humiliated several times and isolated myself, always using pornography as a scape from my problems and a way to get some dopamin since i was 15. Fast foward, since my failed love story with a girl that i really liked when i was 18 (she is the reason i wanted so hard to have a relationship and acted like an asshole with my ex), i started hitting the gym and lost about 30kg. I'm not a muscular guy, but at least i'm not fat anymore. The problem is that i never left pornography and started having ED at 19 and PIED at 20.
I broke up just two months ago. I was very relieved that i got out of something i didn't like, but since my ex started meeting other people and i couldn't do the same because of my PIED, i've been feeling worthless. I'm already in a selfsteem crysis. I have no idea on how many times of no PMO i'm in. I decided to not care about streaks because it makes me anxious, but i know it's at least 8 days+ on hard mode. I'm working out at home everyday, eating healthy and having fun with my friends in mmo's and so on. I know that in pactice i'm in the right path. I'm looking foward to having sex in late june (when 45 days at least have passed). I know that the recommend is 90 days, but in my opinion i have to keep trying to help me about rewiring to real sex (i'm trying to be very open about my PIED to them, and every girl knows about this and are ok about having sex with me).
Just wanna know from you guys on how working out, eating healthy and getting fit improved your journey and ask some tips about what should i do about my no PMO decisions and acts.
Love y'all
