i have panic attacks and anxiety attacks and am not medicated for them. they've gotten better over the years as i've learned to talk myself through the mild ones in my head. but the bad ones the only way for me to come down from one is to have my mom talk me through them. i don't really have any advice, and don't know exactly how i deal with mine, i just know that i do a lot of deep breathing (which i learned in psychotherapy years ago) and some self-hypnosis to help me through.
i wish you luck. if you need to talk, we're here for you :)
