Ive got a really hot temper , how do i calm myself and not let things get to me?

im a lad and my sister who is a year younger than me knows how to push my ons and get me really angry ! i hav something wrong with me wher i cant sit steadily in a room without hearin the click of the door closing, she does things like let the door jst fall swing back without closing properly and then when i shout out at her to close it she doesnt respond ! when she ignores me when im calling her this really bugs me and when we are having, what id call a debate rather than an argument , she never listens to what i have to say when i contradict her, she just goes sarcasticly "yea yea your right" , this really bugs me for some reason and it makes me want to burst out and hit things! ive broken windows by throwing things in anger , i get so angry at the little things like this that she does to annoy me that ive broken my knuckles from punching walls just so i dont take my anger out on her ! .. i just need to know HOW to not react so badly , and to calm myself down , and why do i respond like this? am i crazy ?
