I've never seen fight of flight used with anything but anxiety since it's a fear response. Out of control laughter being included in that makes no sense. Explain how out of control laughter elicits a fight reflex or a run reflex? Fight or flight is explicitly a survival mechanism. Maybe a full on panic attack since that generally refers to something that isn't actually dangerous isn't the right word but anxiety/fear certainly is. PA's ARE fight/flight by the way.
