I personally handle losses by doing push-ups haha and if I still have time to relax after maybe I play some video game for 1 hour to completely forget I had a bad pick on a bad day that ended up with a bad loss. However , for me even losing 20$ means a lot as I usually bet small amounts but overall that would be my forget about betting formula.

You could also try running , play with your pets or anything that will keep your brain distracted for a while.
