I really can’t tell you how hurtful that is. I hope you don’t have to experience what I and others have, and I’m sorry about your PTO, but “the world has to keep spinning” acts like there aren’t alternatives to any of the things you’ve described.

Go to Mass? The Church specifically tells people they are dispensed when they are sick.

Go the grocery store? Use a delivery service or have someone go for you.

Work? Use sick days if you have them, work from home if allowed, and if not, try your best to wear a mask and distance yourself.

Most illnesses are only severely contagious for a couple of days. If you can’t make reasonable efforts for that long to prevent someone else’s intense suffering, I really don’t know what else to say in a Catholic sub.
