Why is my sister such a?

Anonymous
I have a sister who is 17 and I'm 18. She is lighter-skinned than me and has always been more social and gotten more guys which I'm not threatened by at all and sometimes I think she feels like I should be. I am not an airhead but I wear makeup and have gotten lots of compliments on my beauty and how pretty I am and am very confident.
during this quarantine, I have been focusing a lot on inner peace with friendships, relationships, and even just myself. I have taken up meditation and it honestly helps me. I've been a lot more excited lately because of a vacation coming up and I just got a job after not giving up and not being able to find anything because of corona.
Anyways I don't know if it's just her bratty teenage thing but my sister has been so hostile to me over the past year. I graduated high school last year and now am in college so I barely get to see her. Im home right now and try to talk to her when I can but most of the time she just dismisses me or is rude so it makes it hard. My parents are always on my back about having a better relationship with her but she's so nasty to me it makes it hard sometimes. I found out I had to go back to college early and she got so excited and it kinda hurt me. even when we were at the dinner table she was excited about it and we had a family event and they asked me about college and she kept bringing up the fact that she couldn't wait until I left which was crazy because I had done nothing to annoy her and had been nothing but tried to be nice to her. She claimed she was just excited because she gets her own bathroom but I think it was deeper than that. what do you think it is? She has attitudes towards my dad too which she thinks is cute and disgusts me because he still gives her everything she wants.
I am studying psychology and think that maybe she thinks I don't spend enough time with her which doesn't make sense because I try and she's just nasty or shows no emotion. Or that she could be jealous of me. What is it?
