The mask will come off...

Hey nofappers! I want to share my story and early nofap experience to try help other young guys relate to me and to get guidance.
So to introduce myself I'm a 19yo male who has never had issues with female attention but I've had PMO battles since I was 12. I've never been too shy around girls and have only recently developed problems that made me want to change.
I have a beautiful girlfriend who I adore but 7 years of porn addiction (daily) has really pushed me back sexually. I struggle to connect and vanilla sex just doesn't work. I've always had DE through the relationship and over the last couple months have begun experiencing PIED about 50% of the time which really hits you hard as a man when you have an attractive, committed girlfriend yet you don't want to sleep with her.
I put this down to porn addiction... watching increasingly abstract and dirty porn and having to imagine porn to get off.
Now I'm currently on day 10. I am applying creams to soften my penis from apparent desensitization, abstaining on hard mode and trying to better myself every day. My quote is 'be the best version of yourself you can be.'
I hit an instant flatline on day 2 and am still in it. I'm trying to spend time with my girl and be productive all day. I'm trying to sleep better, and have cut alcohol down to 1 night a week. I'm going away for 3 months alone for uni and work so I plan to continue the nofap journey overseas.
My issue comes from PIED. Even though I didn't have much anxiety or other issues, I have seen improvements in this respect... I have been able to do small talk and smile at people in public where I may shy away.
However, my instant flatline worries me. I've had maybe 2 very weak erections since I begun nofap and feel physically incapable of getting one outside of PMO. I want to stick to the nofap plan and am doing so. But I am worried that its not normal.
If anyone wants to give me advice on this flatline Im experiencing and how a 19yo should recover in terms of steps and time.
I'm slowly learning how awful the porn industry is. I want to abstain forever but reintroduce proper masturbation once my sex life improves.
Also if anyone around the world needs an accountability buddy for this journey... please feel free to say hello and we can beat PMO forever.
