My dad... again........?

a long time ago i posted a question because i thought my dad hated me. it has definitely got worse. i didnt want to cry because it would give him teh satisfaction of getting one over on me but here's what happened. i was playing with the dog and mom doesn't like it when she barks so she told me "if she barks again- you leave the room" so i said ok and threw the toy and play fetch. for some reason this is cled as barking and without warning i was just grabbed out of teh room by my dad. ive got marks all over me. its not a "get out" i suppose i could live with verbal commands but he drags me. i cant get up quick enough so he drags me. i told him really loud to get off me because i would have made to the stairs just fine but no... its like he hates me but knows he cant get away with proper hitting ad stuff so does things discreetly to hurt me... other thing hes done are on other questions i posted- like when he grabbed me by the neck and slammed me against a wall. i honestly try to do things right and try not to be bad but he hurts me on a technicality- mom never told me to stop playing with the dog she said dont make her bark. I DIDNT! my eyes are all bloodshot and i need to know what to do now... i dont want to live like this and now realise why my brother hides in his room all day because my dad hurt him too. help me please!
