well when i am not anxious, i take a few minutes here and there to put myself into a relaxed state and really feel that, so that i can say the word relaxed and my body will know what relaxed feels like. then when i am anxious or panicking i tell myself to "relax. a body cant be panicked and relaxed at the same time." i have to keep repeating it but it usually interrupts the anxiety. i also say "i acknowledge my anxiety, i breathe through my anxiety, i release my anxiety" several times till it releases it grip on me.
