Practise mindful breaths. Use the four parts of the breath to bring you into the present. Inhale and bring everything in, then at the top of the breath with full lungs, consciously accept that it’s there. Then, as you exhale, let it all go until your lungs are completely empty of air. Before your next inhale, take a second to enjoy that everything is okay and you’re still you, regardless of what’s happening. The breath is very powerful in helping us think about what we’re taking in and what we’ll let go of.
