Hi there!
I really love the name "Narcissa." It's a great way to make you judge a character without ever really meeting them. The second you hear that name, the word 'narcissist' crosses your brain, doesn't it? I'm sure you already know who Narcissus was, but to help my own answer, I'll give you the 6 word summary: Narcissus died flirting with his own reflection.
While Narcissa did not share Narcissus' direct fate, it is clear that she was only selfless when it came to her own son. And since her son shares and, in a sense, REFLECTS her DNA, her interventions and actions can still be interpreted through the same scope Narcissus' loving his reflection.
In one sense, yes, Narcissa is more keen on protecting her son than herself. However, from a Darwinian perspective, protecting her child IS protecting herself. Draco is her only child. If Draco dies, there would be no one left to continue her line, and considering that most of her family had died without reproducing, it would not be long before the Black lineage died out completely. (Her maiden name was "Black," according to Pottermore.) And, considering that she's both a Malfoy and a pureblood, she was more than likely raised to believe that pure blooded wizards were better than mudbloods and muggles, so losing a pure blooded line would be disgraceful.
I could go on for hours about Narcissa's name, but since I'm not Rowling, it would just be speculation. The beauty of your question is, you can Tweet J.K. Rowling or explore Pottermore for more deep and accurate answers. Considering she made her fortune on Harry Potter, she would probably be more than happy to answer you!
