I find that I get irritated or impatient a lot. I've been working on it awhile (in this great program called Awaken to Joy!) and have made great strides. Initially when I determined that anger was an issue for me I spent some time and got to the heart of it. Why was I angry? That was tremendously helpful. Even if you can't change the causes of your anger, acknowledging what it us that is triggering those feelings can help you to move through whatever it is you are going through.
After that process I found I still had a lot of anger like feelings. I say "like" because it wasn't strong or obvious anger. I was irritated, impatience, frustrated, annoyed. These are what we refer to as derivatives, other emotions or feelings along the anger spectrum. Maybe you never thought of these as related to anger? They could be less strong anger feelings, or it could anger coming out differently specific to the situation. For example, my kids tend to be slower than I want when getting ready to go someplace. I may be concerned about getting to work on time. I don't get really angry because I know they are not deliberately trying to cause an issue for me. I also don't get really angry because I love them and don't want to hurt them. But I do get frustrated and this frustration may come out as a stern tone, or strong words or even some yelling.
It helps to know to know the related emotions and feelings to any strong emotion, be it anger, or sadness or even love. You may say, "I don't get angry" when you still get jealous or irritated or resentful. Just because you call it a feathered, waddling, flying animal doesn't mean it isn't also a duck.
But why does this matter? Expression, baby. I had an encounter with someone once who said that she didn't get angry, or at least that anger wasn't a predominant emotion. That may be true, but anger being one of our primary emotions it's one that's worth some exploration. Ever try to find a house by driving down every street in town hoping that you'll run into it eventually? The same thing can happen with your emotions. You feel bad, you feel stressed, you struggle in relationships and you explore every path except potentially the one that can get to the root of the issue. You cry, you berate yourself, you withdraw, you beg and plead. You struggle to keep a happy face and rise above. What you may be missing, is just getting good and mad. This doesn't mean beating up the neighbor. You can be mad without hurting anyone, including yourself. It may be as simple as that acknowledgment. Yes, I'm angry.
Once you've found the house (or called it a duck!) you can let it go, say you've been there, and move on searching for another more lovely house, one called compassion.
