How to deal with tempers at school?

You just need to calm yourself down. Remember the reason why you get upset is because you allow it to. Change your mind-set. You should start telling yourself who cares what people thing about you. You live for yourself and not for others. Getting pissed off because someone says something about should not be a reason for you to want to hurt them. Like you said your a person with a high temper. So if you allow yourself to get upset for something someone says you might end up killing them. Be careful with your temper. It can cause you to do something you'll regret.
