But by doing this, you can probably get to the bottom of the problem. By talking about how you feel and asking for an explanation, you'll get it off your chest and probably feel better. People sometimes resort to these methods because they seem like an easy way out. It doesn't require much thought or consideration to fight or talk behind someone's back, but it can make things a lot worse. Fighting with physical force or weapons is dangerous and can hurt or kill.
Violence never solves problems, but it does make problems impossible to repair.
And in addition to feeling upset already, you can end up getting into serious trouble. Involving other friends in an argument is usually problematic. In most cases, the friend will just feel hurt, so it's worth the extra effort to talk to him alone. If it's hard to find the right words when talking to a friend, don't be afraid to ask for advice from someone you trust like an older sibling, parent, or guidance counselor. For specific medical advice, diagnoses, and treatment, consult your doctor.
