my girl get's really bad anxiety attacks at times. what helps is when i tell her to breath slowly, and i breathe with her. give this a try. not only will you be steadying your oxygen intake, but you will also be forcing yourself to concentrate on a rhythmic task, which is similar to meditation, and it will help you relax. don't think about anything else but your breathing. breathe in, hold your breath for "one one thousand" then breath out. . "two one thousand" keep it as mechanical as possible. give it a try next time you have a panic attack and message me with the results because i'd like to know if this helped you. good luck!
