I'm glad you posted an update. I had to chuckle about your comment "living like racoons". I think we all are feeling that way these days. People are out "hunting for food, toilet paper and paper towels" in my area.
I am glad that you and your children are doing okay and survived the worse of the virus. Sorry to hear that your xw is suffering from the symptoms at the moment. Hope she is taking care of herself and staying in isolation.
Hang in there and keep posting to let us know that you and the kids are doing okay.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
