You are not alone. My mother would sing it in times of her personal stress as an example. A person may have no personal awareness stress has built up or is building.
A substantial percentage of the population take meds to deal with where it can lead to.

I have been tasked with attempting do reduce the stress level of one of our older daughters. She is quite a distance away. They have their business up for sale and think this virus issue will reduce chances of a sale this spring in all likelihood.

She is far too busy trying to decide on almost day to day changes. To meet the new constant changes with the business. Driven by government edicts and peoples concern over this virus issue. I hope it is working as I notice she seems to be cooling off a little in the last few communications.
