... (I quote) "lovely, you need to sit on a chair. You're having a panic attack, it's okay." It's probably not okay but she put her hand on my shoulder and said "you are not going to die, breath. Just try to inhale." She had suffered with panic attacks and she said that wherever you are and whatever is going on if you start to lose control, sit on the floor. Forget the exam, clear your head put your hands/ wrists on the floor/ walls and cool down. Breath as much as you can and if you have a drink, sip it gently.
