i had been feeling anxious all afternoon at work... occasional palpitations and feeling a bit floaty but i managed to keep the feelings at bay... on the way home was chatting to my work pal... and then got a funny pain in my chest for like a split second then wham fealt hot, faint, sick, head spinning... i came off the motorway at the next exit... then had to try to regulate my breathing and get myself home... when i got in i jst burst into tears... i have had loads of panic attacks but never in the car... i was so scared.. it was awful... has this happened to any of you?? what if it happens again???
