Am I right to be irritated?

So I got a message from my mom a couple of days ago saying she was in the ER because she was having a hard time breathing and had a really bad cough. They said her lungs looked like they had obstruction and her tests for flu and other tests were negative so they sent her home with breathing treatments.

They won't test her for covid-19 but they told her to act like she tested positive because she had symptoms and to stay home for two weeks. She is in so much denial about this saying she doesn't think she has it because she hasn't came into contact with anyone that has it even though she works in a freaking hospital!! she can't even take a breath without coughing up a storm.

Now here is the part that really irritates me is that she lives with my brother and he is still going to work even though he could be living with someone that is contagious!! No wonder it's spreading like crazy 🤦🤦
