Sometimes we do this because we feel there's no one to talk to. I've found I can talk it out instead of allowing it to build up, and once I start talking, it keeps me from taking myself too seriously. That also helps me to see the best side of things and not focus on the negative. We need to realize that things are not all good or all bad. High school kids can be melodramatic.
High school is high school.
People will get made fun of, but that's no excuse to take advantage of people or to motivate yourself into violence. I've heard lots of people talking about warning signs and things to look for. Parents play a big part in that. Kids become detached from their parents and other kids, so kids lose touch with reality. One way to prevent that is to improve communication among family and friends.
