Two things help me a lot whenever I have anxiety: deep breathing and laughing. Not at the same time, of course.
I also got a boost from the homily at Mass today. The priest reminded us of the Bible saying "Keep a sense of humor,
even in the most difficult times."
I also keep busy. When I'm doing something, anything, I forget anxiety and worry. My darling dog Annie is keeping me busy...
she's getting on in years and pees in the house a lot, usually on the kitchen tile floor and not on the carpets. I keep busy mopping it up. haha.
