What if I'm on the verge of crying?

Practice a deep breathing technique. Breathe in for 4 counts, hold the breath for 4 counts, exhale for 4 counts, and wait another 4 counts. You can also drink water, doodle, or use positive self-talk to calm yourself down. For example, you might say, "I've been this upset before and I've made it through. What skills do I have in my toolbox to manage my emotions for right now?"
