Libby Congratulations on going a whole year with out panic, you've abviously been strong and smart to do that. Try and hold on to that positivity and see this as a little "blip" that caught you out. The xanax should help you out, try and keep your mind occupied, read or see a movie, something that will make you laugh
You may feel a bit anxious over the next few days but that is normal after an attack, just focus on the positive and remember how strong you are!
