Have you ever been angry because of someone/something that you know you probably shouldn't be, but you couldn't let go of it anyway?

Vent in writing to no one and get it out of your system. Start out letting the emotions fly, then examine the situation from all angles. This is most often what I use my journal for, regardless of whether my emotions are justified or not.

In one situation involving my sister-in-law I was hurt for a long time, longer than I should have let it affect me, and sometimes I would get worked up about it and actually get angry. If you get me talking about it I can get worked up all over again. I think it continues to stay “alive” because I still have to deal with her, she still does hurtful things, and she would not talk about it and clear the air.

Emotions aren’t bad in and of themselves, they have to be released in a way that doesn’t hurt yourself or others, so I agree with @hearkat that journaling is a good idea. You don’t want to deny what’s going on or judge it – they are what they are – repressing and judging just makes things worse.

Let the anger pass through like the storm it is and then you can figure out what needs you were trying to get met that weren’t, and see how you can get them met in a healthy way.

If someone (real world) really annoys me I’ll retaliate with practical jokes. That makes me feel better. There are just so many things that you can do, ranging from mildly annoying to shock horror.

Vent to a trusted friend.

Write an angry letter to the object of your anger (with no intention of sending it). Then burn the letter and let your feelings go as you watch the smoke drifting off.

Stop judging your feelings. Accept them. Perhaps try to understand what in your past makes you feel this way even if you are consciously working not to be whiny or entitled in your life now.

Since you specifically say “ever” the answer has to be yes. There was a time, a long, long time ago, when I did not know how to control my emotions, and I just let them out all over the place.

I don’t like being angry, I don’t like being sad, and I don’t like being frustrated, so I took it upon myself to learn how to control my feelings. The current answer is no, I have learned how to avoid that situation.
