how do i get people to stop perceiving me in a certain way?

[Lena]

this has to do a lot with my family. i have a big family, but they all perceive me in a wrong way. they always say to people i just meet, " OH don't mess with lena she has a bad temper." they're always comparing me to my brother who is a total a- whole. then i have my teenage nephews. ( i'm only 19 myself) they always introduce me to people and compare me to a man. they tell them i fight like a man, and that i am like a man. this makes me so mad. i always tell them to stop saying that. but no one listens. i know i am independent and i do cut the grass and do yard work, and fix things since no men live in my house, and i'm a tuff girl, but does that make me man like? people i know that don't know my family are always calling me a girly girl, prissy and stuff like that. i wear makeup everywhere i go. i am not ugly. i get complements all the time from strangers and friends, but my family perceives me the wrong way all the time and it ruins first impressions when they're around me. how can i get my family to stop? it drives me nuts. i've told them to stop, but they still do it. and when i say my whole family does it, i mean all. including cousins.
