I think this is one of the hardest aspects of MG-prioritizing and doing it in a way that both we and those around us can understand.

People can rather easily understand and be empathic if you are unable to do everything. But, they (and you) find it hard to understand that you can do one thing (of your choice) and than nothing more.

It seems reasonable that if you put extra effort at work, you can do so at home when you come back.
It may also give the feeling that you don't care about your home if you use all your energy at work.
Or that you have the energy to do what you like, but none left to do what you don't like.

You and them have to find some reasonable consistency in your performance.

The way to do this is to find a new balance of work, leisure, household chores within your changing abilities. Increasing all with each improvement and decreasing all with each worsening.
