Brenton, Welcome to the Eating for IBS Diet board! You may want to check the research library section. There was an article recently about how anxiety, stress, depression, etc. are linked to IBS. I have had depression and panic attacks in the past, and now have been diagnosed with bipolar disorder (manic depression.) I know sometimes a small dose of an antidepressant will help with IBS symptoms. If you are not already taking one, maybe you could talk to a doctor about this? I know they have helped a lot of people with IBS. Do a search on the boards for "antidepressants in the treatment of IBS."
