I'm wont to think that it's more selfishness plus self-centeredness than it is true narcissism. Along with
video, true narcissists are deeply hurt and vulnerable and drag other people down to cope with said vulnerability. Super toxic. I dont think I'm that toxic but I could be very toxic to the selfless and more self-aware.
Self-centeredness can come from a myriad of things. It is, nevertheless, frustrating as most relationships should be 50/50 and not everyone can spend time listening to your woes. A hard lesson learned.
Also, cool video. I like Dr Kirk Honda who explains narcissism in further detail. Edit: I wish I wasnt self-centered but it's a hard habit to break out of, for me anyway. I try not to be.
