Try this, be accepting of what is, try thinking the thought that there is no injustice everything and everything is just is. When the boys play football and a decision goes against them they have a choice to accept it as a lesson and get on or stay and fight their cause, some can see the wrong decision as an injustice and allow themselves to define their identity from it. You too have a choice see it as injustice and allow the situations you perceive to stir up anger or move on. The anger awakening within allows you a sense of identity defining your boundaries. Let me give you an example, a relative of someone who works in my office was rude to me and 2 of my colleagues, I got the same feeling in fact as I had when my father was off hand with me, I recogized this feeling and presented my case to her, she said he was a nice person to her and that I must have been at fault, she walked in mute rage coming back sometime later with a diatribe of insults, so in her reality I had to be in the wrong otherwise her perception of reality was. The next day she was full of allergic reactions and her face was partly swollen.
She has defined her reality using her anger. She had a choice she could have recognised my pain but her preference was to justify her perception ¬that he was a nice guy by saying I deserved to be hurt by him.
Acceptance is less dramatic and stressful. It all depends what you want. We cannot divorce ourselves from the inputting parents. Children deserve protection and love from their parents. And love comes in two main ways learning to love ourselves and honesty. Anger very often comes out in adults because they have failed to deal with it in their childhoods and in time so their children behave in a similar way because no one notices that there is anything wrong. And of course society sees nothing wrong with it.
By accepting situations for what they are you don t need denial and allergic reactions just honesty.
