Well bro I am in a relationship with a very nice female and trying to stay in this relationship but it ain't easy
Had to control my narcissistice rage more than once so far
Maybe you got some advices pour moi 
You had to because your girlfriend would have beaten the shit out of you.
what the fuck is up with narcissistic rage horseshit? You look like a late stage AIDS patient.
Let me cure you right now of this narcissism. Look in the mirror and hear my tough love words of truth.... You have no job,you are in your forties, have no prospects, still lving off a $5000 inheritance you got a decade ago, praying everyday that you slip and fall in front of a business that did not clear the ice so you can sue and pull a Navy Mike, you dont want to work, you live off your mother and the fine folks a from the Polish Social Services who send you a small welfare check every month, yo have no friends in real life, you abuse steroids to get up to a whopping 170lbs at 6 feet tall, you are not attractive whatsoever to even the most desperate hairy fat gay man in a sauna.
In conclusion, you dont have "narcissism" because you have nothing in this world that is attributed to a narcissist. If anything you are a desperate, lonely American living in Poland who has fantasies about being an Alpha male a la Patrick Batemen, but in reality you are more like a skinny version of George Costanza. Basically you suffer from delusions of grandeur and if you were to show your shrink your posts and pictures on getbig he would most likely change his diagnosis because he will know you have been bullshitting him tyhe whole time with your Walter Mitty reality.
HTH; FUDJ
