How to Feel Rage

I am trying to allow the emotion of rage and anger at this moment.
And I’m not sure where to start.
I’m sitting down and breathing and thinking.
Then I went to thinking of the sunlight coming through my window and trying to zoom out of this moment. To remind myself there is more than this moment with my ex repeating the same behaviors in co parenting. That aside from this moment, I’m going to be ok. I’ll be okay financially, and as a single parent and I’ll figure it out and that I’m supported by the universe.
Am I allowing the rage? Or trying to escape it with thinking away from this moment?
I don’t want to feel rage but I want to learn how to be with it. These moments happen about once a moment and I want to get better at being with my emotions.
