Is this emotional/mental abuse?

I'm 19 and for years my dad has always had a bad temper and anger problems. He blows up over anything trivial.He blames everyone for his problems, especially family. He calls me worthless and lazy even though me and my bro both go to school/college and have weekend jobs. Sometimes I get really scared that he will hit me, then sometimes I wish he did so hard that I wouldn't wake up. I don't know how to report him as I don't get hit so I have no proof of bruises. He has got worse now that him and my mum have split up. He made her depressed so she left, now im angry at her cause she left us with him. I feel like im constantly walking on eggshells and Im sick of being controlled,blamed, put down, criticised, shouted at and threatened all the time. Sometimes he comes right up to your face shouting so you can smell his breath and spits all over you. I have no where to stay. I have a bf but he isn't much help :( Please help, I dont know what to do.
