Being a mom means learning (at least) two things you don't expect. One is that every mom is going through very difficult situations, and believing that she is the only one who is suffering so profoundly. And, the associated guilt or frustration is the very catalyst that drives her to find a solution.
When just being awake with my kids causes high levels of stress. I find the best chilling solution is keeping everyone close. Reading, board games, baking, a movie, or something active outside. High energy activity has to be outside, so the energy dissipates in the air instead of reverberating through the house, bouncing off your brain, etc.
