In the mental health field, many of us use the term "healthy coping skills." This term is broad and generic. Yet, if I rephrase it and ask "What do you like to do when you're stressed?" the answers are very helpful.
I can think of a million things to do when we are stressed. Some of my personal favorites include: watching a sunrise/sunset, imagine being at the beach, taking a hot bubble bath, eat chocolate, adjust your attitude, think about the good side of things, listen to music, go for a walk, talk things out with a loved one or counselor, get a massage, accept your imperfections, draw/paint, look at photos, play with a pet, plan a vacation, and there are many, many more.
Finding something you can do when you are stressed is the best way to cope with difficult situations and people. The questions are "What is your favorite? Does it work for you?"
Finally, remember that what works for one person may not work for another.
So, go out there and explore your own life to see what is helpful for you in times of stress.
