I'm trying to figure out if my mother has narcissistic personality disorder (or some level of it if possible)?

her language is laced with "i". on the car ride home, she said "i" 55 times in a half hour in "conversation" with my aunt and uncle. she is very controlling, preaches a lot ("i always, etc") interrupts people while they're talking, is insensitive to other's feelings ("whatever, I blah blah"), tells little lies, e.g. "i'm already here" when she's actually 2 blocks away,etc. help?
