“1. Acknowledge your feelings.
There is no use pretending you don’t feel upset when you do. There’s no point in judging yourself for it, wishing you felt differently, or making yourself wrong.
Instead, own it: “I’m angry. I’m upset. I feel victimized.” Then breathe. Remind yourself that this incident is one moment in a much larger life. Don’t judge yourself for being upset.
Make peace with being human.
2. Find a healthy outlet
Anger is forceful energy that requires release… or a strong ability to refocus.
If you can shift your mind to something better and drop the anger, do so. If you can’t, however, love yourself enough to find a healthy way to release it. You can punch pillows, vacuum vehemently, exercise, walk vigorously, sing loudly, play music, or create cathartic poetry or art. You can journal or write the letters you’d never send, then shred them.
You can pour the pent-up energy into a project. Clean the junk drawer. Weed the closet. Sort through your inbox, or do yardwork. My mom used to make homemade bread and bang it vigorously on the counter when she was upset!
However you do it, find a healthy, non-harmful way to release the energy.
3. Treat yourself kindly
Anger feels like a storm raging through your body and mind. It unleashes a torrent of chemicals in your system. Once it passes, you may feel drained or out of sorts. This is the time to treat yourself and your body kindly. Hydrate. Take an Epsom salt bath, or shower, and imagine washing dense energy down the drain. Put on something cozy. 
By nurturing yourself, you counteract the effects of the passing storm and more quickly return to self-love.
Only after returning to our loving center can we communicate effectively and kindly, or become part of the peace through our prayers.”
