Am I a spoiled teenager?

My parents say I'm spoiled because I stay up late till the night and I get angry at them. The reason I get angry at them is because they say I have stupid friends because I stay up late till the night chatting with them and stuff. I don't want them to come to my house because my family talks too much. It's annoying and embarassing. They also barely buy me any clothes and I'm a teenage girl. I have only 8 t-shirts and 1 pair of jeans. Seriously... I get angry at them because they insult me a lot by calling me an idiot child because of my test scores, I got the highest level but 1 question wrong on Reading and 3 questions wrong on the Math. But none of them say anything to my sister who gets the lowest levels on the Math, Reading, and Writing test. I don't do any of the chores like that because I believe that each of us should clean our own dishes in order to have order and fairness. My mom thinks this is selfish. I just think it's fair. I also get annoyed by my father and sister who like to scream/shout and horse play while I'm sleeping. My mom doesn't say anything about this but when I walk around during the night, she yells at me for making too much noise because I have flip-flops that squeak... So I don't take drugs, drink alcohol or have sex, but my parents say I'm a bad child. I'm in honors classes and I never ever ask for their help on anything because they wouldn't understand. My mom only understands basic English. My dad is male in his late 50s and I'm a teenage girl so... And I don't like him very much either. My mom's in her early 50s and she had to drop out of school in order to help her family financially but she doesn't really understand the differences between our lives so generation gap between both parents...So am I actually spoiled? or am I a normal child?
