Problem with my dad ! I can't talk to anyone.. How can I forget ?! ?

My dad hit me. I didn't say anything bad but he just got out of control and throw in my room and hit me really hard. He hit me as hard as he could so I hit my face to the wall. And my mouth hurts but I can't say anything To anyone. anyways forget the physical. What hurts me even more was what he was saying. The worlds were so mean and hurtfull that right now thinking about it breaks my heart. He made me feel like that I shouldn't have been born and I am only a pain in the family and how .... I can't hold my tears. His words broke my heart into peaces. It felt like that someone woke me up with a glass of cold water.... How can I forget ?!
