i have this thing called an anxiety meter that i visualize in my head. it goes from 0 to 10, 10 being the worst anxiety ever. so when i am anxious, i see where the needle registers on the meter. then i do breathing exercises until i get it down to a four. which is manageable for me. sometimes i see a knob on the meter and i will manually turn down the meter to four so i can calm down faster. practicing this enough, all i have to do now when i am anxious is say dial down, and i can calm myself.
