4 days out of G Y Bypass

Question, how long does it take before I can learn to dive. I live on the coast of NC the best place voted for shipwreck diving on the east coast. My daughter is learning and her boyfriend is the Dive Instructor for Olympus Dive center in Morehead City so hey I got connections, but I need health connections. They said it would be a few months before I could ride horses. But diving I didn't ask about most dives start out around 30 feet here but can also be at least 80. Should I just wait a year and do shore dives. I don't think the dive shops hear can answer this question yet since this procedure has just gotten realatively popular. I know one thing I am not ready to go out on the boat with the way my guts feel!
