Yes doe the things you love, the stuff that is easy to do. That is a good place to start you moving.
As for the work to D, let W do it, ignore if that is what is best for you and your kids. When the airplane is having trouble you put your oxygen mask on first so you can be there for those kids.
When she does get angry tell her you are doing what is best for you and your kids right now, what she wants is not a priority for you right now.
