Did my aunt have the right to do this to me?

I'm 14 now but when i was 9, my aunt used to always ask my teacher if i behaved in school or not. If my teacher said i didn't, my aunt wouldn't give me anything to eat and she would hit me with a coat hanger until i cried. I would always behaved but there would be people who would blame me and then i would get hit for no reason. I thought it was unfair since I didn't do anything wrong and my aunt never asked about my brother or cousin and my grandmother would just sit there and watch me get hit. Her children are worse than me and she doesn't hit them. Could I still report her? since she made me suffer for a couple of months and now i'm still scared of her
