Research: Characters Emotion

Whilst filming today, one of the scenes I improvised with is my character being out of place and sort of having panic attacks. Scratching my neck and legs, looking around dazed and confused was some of the things I came up with. After the shooting I wanted to research more into side effects of such things like panic attacks so if re-shoots were too happen or new shots when we're at Ally Pally I would be able to portray the character as best as I can.
