i seriously believe in learning anxiety management skills~! they are so useful in so many situations~ maybe there is a group near you, or a book you can get at the library or online~ at any rate, having skills definitely trumps not having them~!

briefly, they are:
manage your breathing, if it is rapid, breathe into a paper sack to lower oxygen uptake;

count your breaths, 1001, 1002, 1003, ect, up to 1020, then start again, slow down the count to slow your heartbeat. counting interferes with anxiety;

delay doing anything about your anxiety or panic, just follow the steps and focus on getting thru it;

distract yourself, with anything that requires you to focus and is simple and handy - at home you might read something easy, like a magazine, or knit or wash dishes, whatever engages your attention;

eat something to replenish the blood sugars that adrenelin has burned up, and give yourself at least 15 minutes for the kidneys to clean out the ashes in your blood;

write these things down and keep them with you, until you have made them a habit

practice these skills before you need them, or when you are just mildly anxious, so they will be familiar when you are feeling very upset. i hope you find this information helpful~

best wishes,
Gus
