Run it off.

From "Born to Run":

My personality had even changed: The grouchiness and temper
I’d considered part of my Irish-Italian DNA had ebbed so much
that my wife remarked, “Hey if this comes from ultrarunning,
I’ll tie your shoes for you.” I knew aerobic exercise was a powerful
antidepressant, but I hadn’t realized it could be so profoundly
mood stabilizing and—I hate to use the word—meditative.

I myself have only run for a few months but got such a boost from it.
My attitude toward many things has become a lot more positive.
