Is it bad to hate your family?

my older sister has always been condescending and mean to me my whole life telling me that im fat and need to lose weight and alway telling me what to do and how to act and being mean and teasing me...How do i end and stop this? cuz im sick of feeling bad about myself because of this and its been going on my whole life. im an 18 year old girl btw. i also feel like she hurts my confidence more than helping it and my mom is like this to me also..what do i say to them so they will stop being so mean to me? oh yeah and my older brother is not nice either like if i get a bad grade, he'll act like another parent saying how could you get such bad grades blah blah blah! and i just truly think that my family has ruined me and i hate them for it
