For a little context i have 2 sisters and 1 brother, I am the youngest out of all of them. I am best friends with my brother and best friends with one of my sisters that we will call crystal. The sister that I hate we will call her Julia.

Julia and I have always had an on and off relationship ever since I was young. I'm not gonna go into full details about my whole family but my sister crystal moved out of state when she was 18. so it was basically just me my brother and julia. My parents are divorced, so we lived primarily with our father but I was always closer with my mother. Julia has been manipulating me since I was young and been trying to make me the black sheep of the family. One time when I was 14 she came home with a vape and told me to try it, at this point I was trying to be just like her and do whatever she wanted me to do so she wouldn't hate me. I smoked it but then the next day she told our dad that I was smoking. I never snitched on her. Another time she stole a bunch of stuff from the store and got caught, they texted my brother because he had a number with them but then she pulled me in the room alone and told me to tell my family it was me because " I already got caught with smoking " and " I have a bad reputation with the family anyways " she told me that she would leave me and my boyfriend at the time alone, so i told my mom it was me. She's always been degrading me calling me a whore, bitch, etc. When our dad died it progressively gets worse. She always makes herself the victim in everything and makes herself seem like better than she actually is. She told everyone shes a lawyer and a self taught heart surgeon when she hasn't even gone through college yet. She told everyone she has cancer for attention as well. When our dad died I moved in with my mom and my sister did not like that, she begged me to move in with my dad's fiance ( my dads fiance is the women my dad cheated on my mom with ), she has screamed at my mom and called her a bitch and said " lady listen to me " because my mom took us to california and my sister hates seeing me and my brother having fun. In high school when my sister crystal was in high school with julia, julia told everyone crystal slept with the whole football team and slut shamed her. When i went into high school cystal was out of state at this point, julia was a senior and i was a freshman, she did the same thing to me that she did to crystal. She ruined my freshman year. I went to go visit my sister crystal on new years and we made a new years resolution to not take shit from anyone because i've been letting julia walk all over me my whole life, so i haven't talked to julia in 6 months. But that's not even half the stuff that she has done, she's a manipulator and a gaslighter and especially a narcissist. but i guess shes still my sister but i really hate her for everything that she has done, but i find myself missing her at times. AITAH?
