before i could master my breathing, i used lavender oil to smell - it is sharp and calming at the same time. the scent would go right through the attack and then work to calm me. i would also use chocolate, does sort of the same thing, redirects the sences... tho it does add on the weight if one eats as much of it as i was.... breathing is better, but it takes time to cultivate that skill.

there is also a pressure point between the pinky finger and it's neighbor where they join the hand - you can lightly pinch that spot which is supposed to help - my T taught me that.
Hope you are doing alright... kiya
