First of all don't speak besides identifying yourself by name. Then the only thing to say is "Am I free to go?". If the answer is no, then ask "Am I being detained?". If no, then ask "Then I'm free to go, yes?".
Back and forth. Personally, upon hearing I'm not being detained, then I'd leave.
Second, you can't be refused medical attention. "I feel nauseous, perhaps because I've been refused water and now I feel faint. I need medical attention".
The more you say, the worse you make it for yourself.
