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.
Liz, start seeing a good therapist who helps you find the source of your anger and get rid of it. Do a serious self-examination, find your flaws and read books on the psychology.
Managing you anger is still very important until you defeat it. As Spike says, a punching bag can do wonders. But that's just treating the symptoms.
Good luck.
