Help! Verbally Abusive Dad?

My Dad is very emotionally/Verbally abusive to me,my Mom,and My sis. It feels like he does it to mostly me though. I am the youngest out of 2,and my Dad seems to like calling me fat, ugly,and stupid all the time. And when he's not calling me names up front, he's saying it almost in a hidden way of context, or he's yelling at me about random stuff in the house or about my Mom and how she's a "bad" parent. But to tell you the truth, I love my mom more then my dad, heck, I hate my Dad,I gave no affection toward him what so ever. I just want to make him stop. I'm just a 12 year old here. Whenever he does something he makes me feel like I wanna go crawl under a rock and die or never be seen or heard from again. I have thought about running away and suicide but I am too scared to do both. HELP.
