I used to rage a lot when I was little and once it got so bad that my mom had to take me to a hospital, or so my parents said. It's gotten quite better, but sometimes I still rage for the most insignificant things. Which is strange since I usually get depressed or "dead" during severe crises, but never angry if it's a severe crisis. Sometimes it's because of a sensory overload due to too much noise, and other times it's for something petty like being told to pay attention in class, stuff like that.
