I REALLY DISLIKE MY MOM!?

every other nite my mom comes home from her stupid little job and all she does is whine and cuss on about how she works with"jerks" and "beotches". and then, she gets a brittish accent and everybody nodices(we where at my friends house and my bff asked why she had one ) and her mom just had to have her gulbladder- however u spell that removed and her liver is not looking good and she comes home to nite from visiting her and lites up a stupid little cigarette and opens up a beer. and she smokes so much that i cant even go out of my room without my throat hurting. What can i do besides asking her stupid idiotic dumb self to stop cuz she always says, "I'll stop, i promis, only because u dont like it." and other rediculus crap like that. AND nobody cares and understands exept for my bff (yes the one i mentioned ubove) and my dad says "well ur just gonna have 2 deal with it" and it really hurts and i have no one to turn to and i hate my mom and it is killing me inside and every time i see her drink into her stupid litte straw is hurts me inside so then i hurt myself physically(i do not cut myself and i am not emo, i am not and idiotic freak show like my mom) i just like bite my pillow, or scratch my self so hard it leaves a wilt for about an hour. and typing this really kind of helped calm me down in a weird way.
