You must breathe - take a deep breath now... Things are a little crazy these days and it is not any easier when one has elderly parents to worry about.
Some of our parents have been through some pretty rough times in their lives and are probably better able to get through this period than some of us who have never experienced times like this. You know what Friedrich Nietzsche(German philosopher)said, "whatever doesn't kill you makes you stronger"!
I am sorry to hear about your DH's furlough. That doesn't help at all! It is hard not to get scared at times.
I think we can only take this year one day at a time - just like care-giving. Try not to worry and take those deep breaths. Fix yourself a cup of tea or hot chocolate if you can. It's important to take care of yourself too!
