Possible anger problems?

My family I think has some anger issues so could I have inherited it? Here's some details okay from the time I was like 4 I would have temper tantrums and clear off, anything I could reach. If I got mad enough I would bash my head off the ground or scratch my face, and like cry hysterically and scream as high pitched as I could, but my mom would stop me before I could injure myself. Now age 14 I get angry very easily like at the tapping of pencils and I yell I try to control it but it just bugs me so much that I scream and if they keep doing it I will get up and go over and smack them as hard as I can. I'm also small statured and kids pick and tease me all the time and in 7th grade I flipped and I started crying hysterically and yelling at the top of my lungs and hitting the kid that was teasing me. Then yesterday I spilt some lunch on my pants like milk and ketchup and this kid laughed and I was right up next to him and you don't want to know how mad I was I wanted to take my hand that had a lot of ketchup on it and smear it in his face... The only thing stopping me was the principle she was right behind me. But yeah tell me what you think thanks
