I can swim but I don't like deep water so apart from cruises, I don't typically go out on any aquatic adventures - also I get sea sick and Dramamine makes me drowsy so there is that too

I am so sorry the trainer was not empathetic - I am sure that is one of the main reasons why it put you off the scuba diving - that and the fact that you had not fully recovered from your previous illness

I have heard that scuba diving is actually a lovely experience but am yet to try
