sibling: cat fight. what to do?

I know this is bad but I HATE MY SISTER.

I mean I hate her at this very moment.

so, again, I had a fight with my sister. We fought over an insignificant thing.

I don't really know how to handle her.

I'm like 1 year her senior and we are almost absolutely different. How ironical because most people would thought of us as twins. She's an extrovert and I'm introvert. I'm frank and she's not. We are both opinionated but I'm more assertive and at some point much capable of defending myself in a debate. She often tells me that when I say something, I can always make it appear right. I've always been the debater. I'm always the rational. We are both emotional but she's the histrionic type. You can never confront her or say anything negative about her. She would always take it against me if I say that she's doing this and it's not good. She would always say that I'm putting her down. Well, I admit that at some instances I can be brutal when I say things, I'm always the less compassionate of all.She is so sensitive and I'm not. Every time we have confrontations, she would always cry and tell me that all she could do was to cry because no matter what she'll do I'll always be right. At some point, I tell her of how weak she is for always crying and not even trying to speak maturely or think first or understand first what's my or our point.

When she cries it's always like she's dieing. It's bothering me because she has a heart problem and at some point I feel like she's using it so that no one could confront her.

She hates being reprimanded.

She would always say that she's jealous of me because of my achievements in High School and how she thinks that mama and papa always have something to be proud of me.

She doesn't see her achievements and what she is capable of without having it compared to me. When in fact, I should be the one to get jealous. She's always a happy person, always the life of the house, has a lots of friends, always have lots of things to do with friends.

Maybe, I'm also jealous of her which could be the reason why I easily get provoked by her.

It's funny because despite our usual cat-fight we can easily get along. We enjoy several things together. We like talking and sharing to each other.

We are like the super sisters and then out of no where just fight over small things.

Now we're both in college and living together far from home.

I really don't know how to handle her. It annoys me that she's acting so immature and at the same time hating myself for being immature as well.

I HATE HER- that is my very feeling at this very moment.

but I LOVE HER- I will always love her and always feels like I should always protect her and be with her. Just so happened that I'm not that expressive. I don't appear to be caring even if deep inside I do really care.
