I can really sympathize with you. I am sorry for your loss. In june we lost my husbands father and then a couple weeks ago my husbands grandfather. Been a really tough time. But I will tell you this, I was probably more nervous about having a problem than I needed to be. I thought "how am I going to do this, when I am really upset about something my stomach really really gets so much worse." But with a double dose of Immodium AD. (took 6 tablets. Less than that doesn't work for me on the very bad days. It's safe to do as long as it's not frequent) and not actually having any time to dwell on the subject of pain because of the basic fact that I was at my father in laws funeral and everyone there was as distraught as I was. It's amazing how when you are seeing something so tragic happen to those you love and realize how sad everyone else is, and all the friends and family are around you offering there condolences and wiping your tears, the IBS seems to just disappear. Honest! Not once during the two funerals did I have any problems. In the morning at home, on the way to the church, and before the funeral service started was awful, didn't think I was going to make it, but I did, I concentrated on the service and just let my feelings out instead of leaving them in and I forgot all about the IBS, and just thought about the person we lost and how much they had touched my life. One bit of warning though, the next morning, when all is done, watch out. I was in a ton of pain. Almost like double whammy, my body let me out of the pain when I needed it the most for the services and then let me know it was still there when all was said and done. Didn't last long though. So I wish you luck, take the immodium, and just concentrate on the service, you are there to say goodbye to the person that passed on, not to think about your own problems even if they are totally live altering.
