Narcissistic rage, should I fear for my life...?

I had to confront a very narcissistic family member a few days before Thanksgiving. I knew that they would never admit any fault to their wrongdoing, I won't bore you with the details, so I just sent a few txts and never entertained a phone call about it. I had not shared any of the abuse with other family members until this time, again I didn't try to compromise with the N. I have moved on with my life and I am a lot happier now, especially knowing that the family can see who's the crazy one now. However, knowing how much she hates to be ignored and made to feel wrong and unimportant, how bad do you think our next acquaintance will be? Chances are, I will see her again, unfortunately she is family.
