Or because you know that it gets you stressed out or you feel like you don't want to be there.

Angry, Sad, Depressed (If you're being dramatic!) ...
Take a break from the problem. Whether it is a fight, home work, job related or other. If you are frustrated you are angry and people don't think straight when they are angry.

whenever you're angry, don't let it out and just look at the good side if there is one. If there isn't, think of something funny or something that makes you feel calm. If that doesn't work, go to sleep or something.
