Stick with the subs. The paranoia will go away.
I lost my mother inlaw to a pancreatic attack about ten years ago. We were in Negril when it happened. It was the first morning we were there... The hotel manager came running into the restaurant... There is a call for you from Canada... I hope no one else ever has to hear those words. We left that evening. Shortest Negril trip ever. 24 hours.
SO - take care of yourself.
