IBS D seems to run in my family. However we each handle it differently. For me, it's devastating to have an attack. I'm so worried about an embarrasing scene that I make myself sicker.My sister, on the other hand, can have an attack while out scuba diving on a boat with 40 strangers and laugh about it. Her big worry was that she would go in the water and it might attract sharks. Her attitude is, "I"m not feeling well - too bad what other people think, it's a human thing." I believe, as a result, she has much fewer attacts then me.Sharon
