Is this what is going on with me called abuse? if it is. what should i do?

my father keeps bringing me down and making me cry or get upset.sometimes he hit me and stuf. but almost evry day he makes me cry. d last time he hit me was with a broom in my eye. there was a time he called me a failure and says i will always be a failure. he says he prefers 2 have my brothers as his children but not me kuz he regretz havin me as his child. since he called me a failure i havent been able 2 focus in my studies and i keep failing. i had an exam which i studied hard for but i lost all focus in the exam room an i failed by 1 mark. he starts getting on with me. i tried my best but he told me my best is not good enough 4 him. he keeps hurting me a lot but when i get him in a good mood 2 tell him how i feel, he starts 2 get on an curse and stuff a whole lot more. i dont say anyting more 2 him kuz its just useless. what should i do????
