Hello everyone, I would love some input if you have any.

Though never officially diagnosed, I am show 6 out of 9 criteria for narcissistic personality disorder (and two that are sometimes). This is starting to show more and more in my relationship. Whenever I get into an argument with my SO, I will start to feel more self centered, and when pointed out I feel the need to make myself seem more superior by being right or at least have higher standing. I do often feel as if the world revolves around me, but I have no idea how to change that. I simply find it impossible to put myself in "somebody else's shoes." This is really starting to take a toll on my relationship but it shows in many other areas of my life as well. What are some steps I can take to help prevent myself from falling deeper into narcissism when challenged? I want to work on that before full on looking at my life.

Thank you
