In my household there is not always a moment where to rest. How do you cope with it? And what is your advice for me?

I would try to feel gratitude for being able to do everything You're able to do. Still lucky that you're able to stay busy and active and focused. But no matter how busy it's important to do self-care. It's easy when you have a spare moment to try and do something that needs to be done but it's way more healthy when you're able to be relaxed and happy and feel like you got to do something you enjoy.
