My mother wasn't a narcissist, but I can safely say that my mother is the reason I have BPD. Sure, I was born predisposed to it (since there are anatomical, biochemical, and genetic factors which play into it) and you can say that I'm bad for blaming and pointing fingers, but she was the only parent and the only consistent authority figure I had until I was 15. My mother has untreated bipolar disorder and, looking back, I'm almost positive she's borderline as well. I grew up as the only child, and we were very poor and sometimes even homeless. She told me constantly that I was a mistake, that I was fat, ugly, a b----, that she hated me, etc etc. She'd berate me all the time and then yell at me for crying (invalidation) so I'd just either not cry or go hide somewhere and cry. There were so many times when the roles would be almost reversed and I would have to parent myself, and she would be almost as irresponsible as a child like when bills had to be payed or when I would have to stay home alone without a babysitter when I was eight years old while she worked. And there is so much more, but my story is far too long for this forum.
