She is jealous... She hates me...

She came in late... Our curfew is 10:30pm... Thats the rule in our house...
I am 25 years old and still have the same curfew... I was always obedient, always afraid to break the rules and never broke them on purpose... I always made sure I followed every single rule he set for me... Not just that I was afraid of his furious moments (He never hit me... He knew that words are enough to tame me), its that I dont like making him upset...

Anyway, so she came late, as usual... half an hour late... And he started yelling at her and gave her a punishment not to go out again because she doesnt obey him... She shouted back, yelled, cried, defending herself... And all I could her is my name "eshme3na Heya"... She is basically believing that my Dad treats me differently... That he allows me to do stuff and doesnt allow her to do... But the truth is, its the opposite that is true... But she is jealous... Always jealous of me and hating me... Always finding ways to hurt me or make me sad (writing in my notebooks, cutting off the sleaves of my top with scissors, spilling sauce on my white bag and it doesnt come out, breaking my bangles.... and loads of these kinda things)... And still she totally believes that I am there to ruin her life somehow... She always makes comparisons and always feels like I am her greatest and worst enemy... The other day I discovered that she takes my cell phone after I fall asleep... Not only did she make phonecalls and make my bill grow more expensive, but she reads my messages and stops my alarm from going on so that I dont wake up to pray... How should I define or react to such action of hers??

I sometimes wonder how on earth can we be sisters... She loves making me annoyed or depressed... She never made me anything nice... Always ruining anything that has to do with me... And even when she is in trouble with mum and dad, she related it back to me, or compares herself to me, or their treating us differently...

Is it my fault that I obey rules? Is it my fault that I am the eldest? Is it my fault that I am thinner? Is it my fault that I am independent financially and buy my own stuff?? Is it my fault that I respect my parents and they are both my friends and I am always on good terms with them?

Not just do I mind my own business, I also get her whatever she wants, give her money, accept the fact that she is rude and messy... But more than that I cant tolerate nor ignore... I am tired of her crap and really wish I could leave the house to stop sharing the same room with her...
