When you are angry, try acting opposite to the immediate normal reaction that you might want to unleash.
The one that you are pretty sure doesn't work because the results often aren't pretty at all.
The not constructive anger.
The angry anger.
The one that you sometimes hold in to let simmer. Sometimes simmering makes you sick.
So do the opposite. Do something nice.
I promise you will be pleasantly surprised.
I have found that it often makes me feel better.
P.S. It's not the me feeling better that means the most, it's everyone feeling better, because we're all in this together.
