any advice about this sort of relapse?

Hello,

Today I woke up extremely horny, my mind went wild and I had some strong thoughts about an ex, tried meditation couldn't control/relax it and I did watch some porn for like 15 minutes but I didn't felt doing anything, I didn't felt anything arousing, I think I didn't connected with that immersive feeling when you are doing it everyday.
I felt I want a woman and I felt porn is the wrong place and I closed it before failing in that negative emphaty of really doing anything with whatever woman is in the screen.

I am day 13 now, but I am on a total war with nofap for over an year, I always batle to detach from porn mentality and the behavior after a relapse, just focusing my energy on something else. I was fine all those previous days, had some random thoughts but it wasn't really a battle till today because my mind just wasn't there where porn is.

Wanna know how this relapse is really affecting my progress. I don't care about the counting the days, I only care about building that healthy mentality of not living in my head, especially sexually. It has nothing to do with porn, I only care having this behavior erased from my life.
So what should I expect? Should I expect new cravings? My brain state is like again at day 0? Again, I didn't do anything, it felt exactly like putting a cigarette in the mouth and then putting it back.
I think I need to regain my focus on my goals, this few past hours, I am in the zone of porn metal state, either if I am on this forum or hardcore relapsing(thankfully not), my mind is not at the right place now.

Gonna read this only tonight so I don't have to think about porn while talking here tomorrow.

Thank you.
