breakup made my porn addiction worse

about a month ago i went through a breakup and it has caused my porn addiction to get way worse than its been in a while. all i do is think about wanting to have sex or masterbating. I mean I have always been a masterbation addict but its been way way worse recently. How do I stop?

I mean I have been doing this stuff since i was in 4th grade, its absurd how I cannot stop ever. And to make it all worse, every time i do the deed with myself i just think about her and it just ruins it and makes me feel sh***y. Its just shameful really. I have no clue how to stop or who to talk to because its embarrassing and I would get laughed at if I brought it up to my friends.

Im just at a loss right now, idk what to do.
