We all have a lot to be angry about. Anger is a healthy emotion. It's what we do with that anger and how we act on it that is the issue. Or if we get stuck in it.
It is anger making having others harm you.
It is anger making to have others deny the harm that you experienced.
It's working through that anger to get to a place of acceptance.
Some people move to forgiveness (I'm not one of those people).
But distraction is good.
Awareness that you are getting angry.
And then deciding to do something different.
Maybe CBT will help?
Or maybe deeper therapy to really process that anger and deal with the roote cause of it?
It takes practice to change behaviours. But it is doable.
