Are my parents considered abusive?

Well my dad is nicer than my mom.. Anyways, when I was younger, like age 5, and stuff my mom would always always hit me. I would cry a lot. Ever since then, whenever my mom would yell at me loud, I always shake and move back as if she's about to hit me. I still do this.. But she doesn't hit me anymore. My dad hits me sometimes now. My mom has been really mean verbally to me this year. Like, I'll lie about something not that big and she starts freaking out. My mom has said she hated me. she always tells me i'm gonna get fat, cuz I luv sweets. She says, "**** u!" to me and wen I was younger she would always make fun of me. I would try to holo hoop and she would be like "u look stupid. Don't ever do that again." I was only like 5, or 7! And she still does that. My mom makes me feel horrible. Also wen I was little her and my dad would always make me take my clothes off, get naked in front of them for NO reason when I was 5 and 6. Weird. :/. Is any of this behavior normal? I'm 13. And my parents don't make me be naked anymore. But they always walk on me wen I'm in the shower or changing... Sometimes. And my mom says how spoiled I am. She does take me fun places and stuff which I like.. But I don't feel loved. A lot of people have bullied me for no reason. I've been feeling unhappy, crying myself to sleep. and one time my mom said.. "don't go to school and tell kids uve been "abused." hahah".... My parents tell me how good my younger brother and sister are. My sister and brother can be so mean. They tell my parents every little thing I do. My sister and bro don't get in trouble for hurting me! My whole family in my house, makes fun of me
