Am i being abused?

Am i being verbal or emotionally abused ?... Part of my child hood was good but then parents argued and xstep mom ,dad and mom argued lots cops involved... My mom gets mad for small things like one end if bed sheet hanging lower than other side and stuff.. She yells nd tells me idiot nd more in spanish nd few times she temped to hit me... But now she gets red only.. Grandma and dad call me slow in everything i di ofcourse how can a depress girl be fast minded?! Dad makes fun of me nd then says jk after.... His mood changes.. There allways on top of me nd i barely go out with friends... Im 16 they forcing me to choose my career but when i said physiologist they laughed nd i said police woman they laughed more but they like if your brain don't give enough for university then do a 2 year course to get certified... And they always compare me with other girls.. And in family trips or when family over grandma controls me and lets everyone else get the goods don't wanna be the top but because I'm youngest besides 4 yrs bro that doesn't mean a thing... Im so depress i feel worthless and like **** I've cut tried committing suicide.. And everything i try doing right its wrong so i dont understand... Like dad got me new ps3 this tear cause asked for used ps3 so its cheaper but grandma started telling me off saying your father got you this **** that you prob not gunna use keep it in box incase dad wanna return it imma tell him ... I kept it.. I cry every night..
