Could someone please explain in detail what this is? I have a few friends who suffer with this and I'd like to know more :)

Always ask Wikipedia first :P

this (http://www.mind.org.uk/mental_health_a-z/8001_anxiety_and_panic_attacks) might also be useful, wikipedia is okay but often medical or charity sites are a lot more easy to understand :)
