Regular vagus nerve stimulation through humming, loud singing, gargling, and diaphragmatic breathing can be really powerful for calming the nervous system. Be sure you are also exercising regularly, getting adequate sunlight, not spending too much time on electronics, and including GABA-promoting foods more regularly in your diet like broccoli, almonds, walnuts, lentils, bananas, beef liver, brown rice, halibut, gluten-free whole oats, oranges, and spinach. You might also consider supplemental support like Everyday Stress Relief or GABA Calming.
Additionally, take an inventory of what you need for restorative energy to tolerate the limitations of being at home such as reading, music, regular virtual gatherings with friends, creative activities like drawing, writing, etc., and/or learning something new like a language. When we fill our cup with things that energize and restore us, our stress tolerance for those things that are out of our control greatly increases.
Hope these help!
