I'm sure you never find such a fuc.ked up elder sister.....wana get rid of her?

She is sick and she suckss badllyyyy...my fu.cked up elder sister thinks she is soo dominating that she can do whatever she wants....today morning she found that the landline phone bill came upto 1800 rupees(which obviously my dad is paying) which i think is fair enough because...i made calls to agents for searching flats that we wanted to purchase...she came howling at me and she said" dont make phone calls from here"!!...you may read my other question to know how bullying she is....but today while she came rushing to me..i said...before fighting with me...just listen i dont make casual phone calls or any personal calls from here coz i have my cell phone...and before any further explanation she took away the whole landline phone with the connection to her room and she said call from your cell phone ..i wanted that land line for some very formal calls....or urgent calls...and she just snatched it..i have been surveying and calling to agents this long to know about flats that are on sale in our place...and she does nothing rather than just sit and eat....and then she expects me to go and survey the flats..i didnt want to do this..but coz mum and dad wanted us to purchase...so i had to do.. ..and she will do nothing...she wants everything ready made which must be freely available to her..... she's soo selfish....seriously i dont even want to stay with her....what should i do..??you know she also beats me with...which you get to know in my other question.about how pissed off i am with her..she is also jealous of me ...my boyfriend my friend...and my looks...my life...she cant stand me with anything...
