Crazed - it seems that the narcissism could come from the point of martyrdom - we (subconsciously) feel better when we sacrifice ourselves
'for someone else."
I can see both sides though. I was raised the opposite of m1k3. It was loving supportive home where I was told I could do anything I could dream of, and be anything I desire to be. Our needs were put above all else - above my parents financial abilities, above their relationship, above their time constraints. They put on a perfect front - we NEVER saw an argument, or stress because they were in dire financial straights. Our world SEEMED perfect. We were told we were the best, the smartest, the funniest - and all probably developed some ego and self contentedness issues in part because of that.
In adulthood, it has turned to "I am obviously always right" - and yeah, often at the expense of someone else's feelings. 9 failed long term relationships and 6 careers later, I can see it.
