Anger Management Support Group
Anger management commonly refers to therapeutic techniques by which someone with excessive or uncontrollable anger can control or reduce their emotions. Typical examples include the use of deep breathing and meditation as a means to relaxation. Psychologists recommend a balanced approach, which both controls the emotion and allows it to express itself in a healthy way.
However I don't think you should be looking at it as a way to dispense your own frustrations on others. You should find a better, healthier way to get rid of that anger, and resentment.
