How do I kindly tell my sister I hate her guts?

Omg this sounds really weird but yes, I hate my twin sister a lot. I hated her since I was 12 years old but I didn't have the courage to tell her to stay away from me. The thing is that she loves me but I don't love her back. We still live with our parents (I go to university though) even though we are both adults so ignoring her won't be easy. And staying in my dorm isn't an option because my roommate is a b*tch and comes with a new boyfriend every month. And the stupid headmaster doesn't do shit.
The reason I hate her is simple: she thinks she can get away with everything. Like really, our parents blame everything on me even though I'm an adult woman. And she never supports me. But she still texts me everyday asking how it's going and how she loves me.
I don't know how to tell her to not interact with me. I don't want to appear as a first class asshole being like: Oh hey sis, just letting you know I hate you so don't interact with me. I want this to be done professionally and like mature people.
Do you guys have any tips?
