It definitely depends on the degree of stress and the situation one finds themselves in. In most cases and for me, taking a short walk or having a nap always solves the issue, as this resets the system, so to speak.
I think having a balance between putting family first and prioritizing oneself is usually the way to go, since we're each part of a whole but also have our own selves that's different from the whole.
Absolutely, it all depends on the mood in that moment.
