In childhood our brains and body are not fully developed, they haven't matured.
This means that often we cannot fully process our experiences, so, the emotional energy gets stored somewhere in the back of our minds and in our bodies. We continue to cope and survive and move forward.
The older we are the more experiences we have and the more emotional energies accumulate, like building pressure in a pressure cooker.
Anger is an energy that often gets shut down; we don't get to express it, so our body stores it, until it becomes unmanageable and starts to spill over!
Anger management teaches you how to manage the symptom of anger, which means, you still have the anger to deal with.
Anger RESOLUTION has you process your experiences (including difficult relationships) until you discharge the emotion(s). When you fully confront and process your experiences, the energy attached to them gets discharged and the experience is resolved.
You don't have the anger to manage - it's resolved!
When anger energy is discharged it reduces the triggers and you feel better and function better.
