You are doing all the proper things to get through the next few weeks. Your daughters will be just fine and are probably enjoying not having to do the dishes, etc.
I also think you did the right thing by "locking your parents up". It's better to have them safely in their own home and having others bring them supplies if they need them.
Please stay safe and healthy!
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.
