Is my stepmom a *****.. What do yu think....? READ?

Ok so when i was like around 3 or 4 my parents go divorced and my dad had custody of me. i grew up with him and when i was 6 my mom died of a heartattack. when i was 7 my dad almost lost his life because he fell into a pit of boiling water. so he dated a few people shortly after my mom died although they we're divorced already before and married one woman when i was 8 or 9. i was an only child and when they got married they had 3 kids together along with her two sons from a previouse marriage.. so now i'm 1 of 6 from an only child. Yes it sucks. but i liked this woman and she seemed really loving.. Now, she hates me. she calls me names that i wouldn't even call my dog. she constantly is yelling at me, because i'm the oldest child in the house. (15) & she has said some really mean things to me like: "Well if you don't like me go live back in that small little house with only your father and have no family..." Or something like "your disrespectful little *****" she's harsh and mean. & what bothers me more is my dad is now siding with her and is convinced i'm a *****. they made me move this year from new york to myrtle beach and now i have 0 friends and no one to talk to. i really hate my life.. what do you think?
