This exact same thing happened to me during my most recent diving trip with two friends to Egypt. I went from "yay, wonderful, it's great down here" to "whoa, I'm gonna die down here" in a split two seconds at approx. 32 meters.
I'm in training to become a rescue diver and I'm very happy I am - instead of letting instinct and panic take over I instantly fell back on the drilled "stop-think-act" failsafe and started to focus on my breathing. I also took hold of my regulator to prevent me from spitting it out in a panic attack. We ascended slowly and within 5 to 10 metres the panic subsided. We suspect that it was a small co2 narcosis, quite possibly on account of me not drinking enough water prior the dive (it was a very early morning dive). But, my regulator has also developed the tendency to start to "whistle" when at 70 bar or less, so it might be a reg in need of service. Will see to that asap.
