My Biggest Complaint About Sister Taking Advantage of Me

my sister has been playing everyone around here. she is my room mate and she has the audacity to go talking behind (all lies) my back to MY closest friend. Now im always forced to watch her kid for her. she’ll get up in the morning and wake me up to tell me that she’s going to leave her and if its ok. wtf how can it not be okay. youre dressed and about to walk out the door. or even better she’d text me that she’s left her in the room. to make matters worse. she tells everyone that i never babysits for her and that she has no one to do it so she doesnt go to work,
She tricks her money off to guys left and right. and for those of you who dont know what tricking means its when you give your money away to someone for no good reason and then your broke. anyway she gives her money away and then asks my phucking friend to loan her money for her portion of the rent and bills. And my friend is such a sweet heart that she lends it to her. Oh and she always always always babysits for her. Heres the kicker, my sister will NOT babysit for her though. she tells me all the time how she cant stand my friends daughter and hates when the little girl is around. that is so two faced!!! my sister loaned my friend some money and now she cant stop talking about. she complains to me about everyday. I wanna tell my friend all the **** she says about her but im not for the drama . I also havent told my sister that i know all the up things shes been telling people about me. i just walk around like everythings okay. I might end up bursting up on her.
