Why do i get insanly pissed and stay pissed for up to 2 days about the exact same thing?

ok well im 14 a pretty chilled dude , and it takes ALOT to piss me off but when i get pissed i get REALLY pissed and just want to hit everything i see nomatter if it even has anything to do with what im mad, when i get mad my heart starts to beat insanly fast i feel x10 stronger and faster, everything will like be in a haze (as if i were wearing gles that wernt made for me) my lungs feel really light and i can breath insanly well and i just want to break or hurt something.at ive broken my hand on walls and other stuff about 3 times, and broken so many other stuff in my house a day ago i punched though a mostly solid door... the worst thing is ill stay mad for a long time but then ill get over it in a few hours, but out of nowhere i get PISSED about what i was mad about 2 hours ago and continue to hit stuff, some of the things im mad about arnt the big eaither, ill stay in this like ragemode for days. its not a random rage its like a build up rage i feel myself getting more and more pissed every second when im mad a even little things why am i getting so mad? i dont get why i dont get sad... i just get pissed never sad at all
