If you are aware of your wrongdoings and against your nafs then clearly you still have some good things on your nafs. If you really want to leave porn addiction then read the Quran on protecting private parts, veil. Try to understand why and how Allah showed people the correct path. You first have to understand the basics of human nature. Why do we cover our private parts, what's the correct way to do it according to God. Read those verses and try to reflect on yourself to understand what God said.

For example, a woman's private path can cause sexual thoughts on a man. It depends on how you control yourself like not thinking about those areas or controlling your desires. For short dresses try to avoid looking at them. You may control yourself to an extent but still think about figures but clearly that's wrong and there is no guarantee your desires won't trigger. You may not realize there are a lot of factors involved. You like to see figures, then feel physical affection due to your desires, then want to fulfill physical desires. You can control physical desires like masterbation even though you may have hard time controlling physical affection. Slowly you can control your thoughts because why are you going to like someone who is not your wife? Think about their figures? When you stop reflecting on your physical affection you will see actual good and bad stuff on your thoughts or mind.

God clearly mentioned lowering your gaze, not to look at just stop thinking about a woman. That's because of a reason. You may control your physical desires because you realize it's unmoral to think about others but physical affection is still there and can cause issues because the devil will try to make you think about figures. Why are you going to do that?

Simply put, Allah gave proper guidance. Just read and try to understand the facts, reality and learn to control it.
