Mom Worry

Hi ladies my three year old has been home for two weeks because his daycare closed because of positive Covid cases. He and myself ended up getting Covid. He goes back to daycare tomorrow and I go back to work and I can’t help but to feel nervous and anxious. I worry he will be exposed again, I worry he will get a cold or be sick. I can’t turn off the worries and I know I’m overthinking it but I still worry. Any other mamas been in my shoes?? How do you turn your worries off??
