I'm having a panic attack.

John: 'I can't breathe! I feel like I'm going to faint.'<br>

Alice: 'You're having a panic attack, John! Let's get you some fresh air and try some deep breaths.'

John: 'Stay calm, Alice. Let's sit down and try some relaxation techniques.'

Alice: 'My heart is racing, and I feel dizzy. I think I'm having a panic attack.'<br>
