My Bad

I know that i have this problem for a long time. Sometimes, i just can't seem to cool down and i get angry very easily. At times, every little thing just ticks me off makin me very, very angry so angry that i am capable to harming people. However, i’ve been tryin to control my anger but when i do, i feel a tightness around my heart and feeling faint too. There are so many times i wished i could just kill whoever it was who irritated me (sounds crazy right?). When i get angry, it doesn't really matter who you are. I know that i'm capable of violence but i can’t do this to other people -_-

Before i write this post, i saw a movie by the way and there was a character-i-guess-you-could-call "angry" and "annoying" and i thought, "Hell yeah… that could be what other people see me as sometimes..."

Honestly, i think it's affecting my life in a serious way. Sometimes, i feel like this horrible person that people think angers quickly. I really want to stop being that s*hit. How should i really go about it? I've tried almost everything already, guys...
