Is it normal that i don't like my own family?

I have always been closest to my dad. That's just how it's always been. Daddy's girl. The only problem is that besides my dad, I can't stand anyone else in my household. My sister is just a little under two years older than me, but she acts like she has a good ten years on me. She treats me like a child and every chance she gets, she makes fun of me. "Fifteen and never had a boyfriend," "You're so fat, that's why no one likes you," "Mom and Dad like me better, can't you see that," "You're such a stupid idiot," and so on. Yeah, sure, we share interests, but I think that is solely due to the fact we have lived with each other for such a long time. She's a bully to me and tries to act like she knows what's best in life. Just a few minutes ago she tried to choke me (I have the marks on my neck to prove it) because I took out my headphones. I told her my ears were hurting and I would put them back in soon, but to just give me five minutes. She came over to me, slapped me, told me I "better put the goddamn headphones back in" then started to choke me because I held my ground and said not for another five minutes. But enough of her. Now my Mom. I don't really know what to think of her. Sure, sometimes she can be nice, but she's ALWAYS on my sister's side and it seems like I have to beg and plead for her, just this once, to be on my side. My Dad is the one who is (almost) always on my side, unless I am being totally unreasonable and he will tell me so. So now knowing what you know about my sister and Mom, do you think it's normal of me to resent them for being in my life?
