Take a break but only if you've earned it. Be kind to yourself, but do not fall into the trap of overdoing it.
Self-care is only caring until it isn't for the better good
Self-care is no longer caring if it hurts you more than it should.
So, go ahead, and take a break take a day to go slow, and wait- wait for the emotions to cease until you breathe with ease and know with certainty you will be okay.
Then get up and don't let yourself be late for that meeting, or coffee, or dinner date because you deserve a life of love, not hate- so continue living, and if you're tired, take a nap.
