Ending1: Count quickly in your head, keeping your mouth shut until you feel calmed enough to talk. Repeat this as many times as you need to calm yourself down. Ending2: It doesn't need to be long, just enough to start a new breathing rhythm. Do not hold so long it that it starts to get uncomfortable or you feel dizzy. Ending3: Breathe through your mouth, not into your diaphragm. Hold your breath for several seconds until your diaphragm is adequately controlled with no more tears. Ending4: Breathe out very slowly to adjust to the increased pressure on your diaphragm muscles. If your breathing slows, hold the breath for another three seconds.
