Yeup, I'd urge everyone touched by panic disorder to come here and have a read. As for how to be helpful during a panic attack. Umm, I think the best thing they can do is just be there. Something not to do is say "don't worry" haha, that's the classic thing we don't want to hear! Instead she could say things like. "I'm here, and when this is over, the world, and me will still be here." I understand it's hard for the person watching us panic. But if people are panicking around us, it'll only add fuel to the fire! If she's worrying about a heart attack run down the list with her and tick the symptoms off. Pain in the arm, grey colour to the skin. To reasure her that it's not a heart attack. Also it couldn't hurt to go to the doctors with her and get checked out. Have the doctor explain the physical changes of a panic attack.
