Is my mother narcissistic or just arrogant (or insecure?)?

she is always talking about how great she is, how she's 'on a superior plane of life' or something like that. she's extremely judgmental. always makes little nasty comments about people who 'aren't on her level'. doesn't admit to her faults. like, if she is bad at something, she will say she is excellent at it, or just say that it doesn't matter/ is overrated anyway. is NEVER at fault in her mind, if she admits to it she's clearly not. like, today, she wanted me to design her flyer or whatever in one hour because she hasn't given me the information all week. i said i'm really busy today and that i might not be able to make it in just one hour! i agreed to make it LAST WEEK and she never gave me the information, and suddenly gives it to me NOW and expects it done NOW. she says "oh, its my fault"/ victimizing herself then starts saying that /I/ have horrible work ethic and telling me how "well, i'm never doing business with YOU again :)" and giving ME all this attitude. i can't stand it! what is this??
