Am i wrong for hating her?

i hate my mother so much. she is evil i swear to god like she has no friends and is so miserable so when someone looks worse than her she will jujst continuously talk about them nd put them down just to make her self look better. i am a very good person i know i am nd try my best to do the rite thing but she dontesnt care about me at all i can see it. she says im a sopiled brat but im not i love my father he is my best frand nd her understand because of course my parents are separated but if shes in a bad mood she would just go crazy nd call me all types os name like ***** lil ****** and etc i dont kno what i did to make her hate me but i really dont care any more she used to make me cry like every day btu i try to tell my self dont your tears on her shes not worth it but i cant help it because she really hurts my feeling nd i just cant figure out why or how she gets to me. ok im not gonna lie i do yell back nd defend my self but im not gonna to let her push me and smack me around, call em out of my name nd physically threatn me she doesnt kno me at all i get along with every body my great aunts,father, friends but she just seems to be the only person who so deeply resents me . everyone except my father wen i tell them the stuff she does to me that dont belive it or say that not liek your mother r some ridiculous stuff like that but they dont know her, no one knows her like i do because i see whats really at hand because she puts on a front for every else, why cont she do that to me. they say she been through alot but seriously i dont pity her thats her fault i dotn care it was her choice to get pregenant and get a shytty job and not go to college its not lot were broke she make alot of money but doesnt kno how to handle it and they say her job is so stressful well liek i said thats not reason to take it out on me or my little brother, do you think im the bad person for hating her? she thinks i owe her somthign when she says oh i bought you this and that and im like your suppose to because your my mom your suppose to care about me i dont care very much fro you buying me things but i want you to kow me and spent time with me or have some type of interest but at the pijnt were at now i think its pretty much impossible cuz i cant if stand to be in the same room as her, wen she talks it makes me want to just curse her out but i dont i just walk away, because are so different
