How do i know if my parents are emotionally abusive?

ok, well im 15 and i HATE coming home every day b/c i know there will be something that will make one or both of my parents mad, usually its little things like the unlocket front door or a light left on, and theyll start yelling and screaming as if i just killed someone. my dads the worst one, sometimes hell get a little physical but not enough to leave a mark so my friends wont see, but he screams AL THE TIME. and pushes alot. realy hard sometimes. im not just beind dramatic am i? (thats what they say when i start to cry) theyll say things like "dont put on a show, no ones watching" or "you wana cry? you really wanna cry? come here ill give you a reason to cry..." etc. it is horrible. i cry alot and i HATE living in my house. is it emotional abuse or am i realy just bing dramatic?
