As a parent in a crisis situation, your job is to provide emotional stability for your kids. So you need to ensure your own physical and emotional health first (see also: "put your oxygen mask on before helping others"). So if "home school" has to take a backseat to showing the kids that "this is different, but this can be healthy/interesting/stimulating too", then so be it. And some days are good homeschool days, some are less. Take each day as it comes. However, juggling work and home school is just impossible. In a two salary family, someone needs to go on disability or take unpaid leave or whatever. Your kids need you right now more than your boss does.
