hi everyone: I suppose one needs to feel comfortable expressing one's anger in constructive rather than destructive ways. Emotions/feelings feed the thoughts/thinking, then the physical/doing. Anger is not an evil emotion, just an energy needing direction. That choice thing again, what do you choose to do with it? It depends on what or why you are angry. Sometimes you may not even know why.
First things first, identify the anger. Is it an anger you feel toward someone else - a real or perceived hurt
Is it an anger toward yourself? (I should have done better!)
Is it an anger toward someone who is angry with you - (so you both start yelling)
Is it an unresolved issue of long ago?
There are more reasons, of course. Next is to figure out what you are going to do about it. Use the W's. Who, Where, When, What, What and How. Yes, two whats. Who do you need to express your anger to? Why do you have to express yourself? What outcome are you looking for? What do you want to say? When is the best time to do this? Where should this be done? and lastly, How should this be done?
Just some things I learned at support group I attended. Hope it helps.
