I've been reading through all these posts and I can't relate. My friends and family are so supportive. Before I go over to any of their homes they ask me what I can eat.
A year ago my family gave me a very hard time for losing a lot of weight. My brother called me up and chewed me out for having an eating disorder again(something I took control of 14-15 years ago). My brother and sister changed their attitudes once they understood IBS, but not right away. Now when I visit my sister she makes IBS safe meals and I really apperciate she did her own research to know what to feed me.
Sometimes it takes longer for people to understand. Sometimes I think people don't know how to handle situations, so they avoid dealing with the issues. Give your friends some time and hopefully you can educate them on your turf. Good luck!
