Alright. It was a genuine question - ok, they said you weren't detained at the beginning, but the moment you were forbidden to use the phone and the door was guarded you effectively were. I'm just surprised that didn't trigger the "I want a lawyer/I will leave now" impulse. But I admit to not having been in the same situation myself, especially not in a dangerous country like the USA.
The symptoms you described are most probably caused by an extreme low blood-sugar level - combined with the stress of the situation, you were close to collapsing. Or it was simply shock, dangerous as well. I was glad when not reading about that collapse.
Edit: Just to make that clear - the situation wasn't your fault regardless, didn't want to imply that (just realized one could interpret my comments that way). Absolutely unacceptable treatment by both the airline and the police.
