"Anger"

When Im angry I get stressed much, I lose patience and I usually talk frustrated, I try to calm and i sometimes hit things.
The last time I get angry was a year ago because they arrive late school, that day in the city had a lot of traffic and the subway was moving very slow, and to my bad luck I was to arrive early because it was exam application.
I arrived ten minutes later and the teacher let me go to the classroom.
And from that day I try to sleep early to wake up earlier and arrive early to school.
