Hi there- I was reading your posting and was wondering if especially since you were diagnosed with IBS, if your doctor ever tested you for celiac disease or gluten intolerance-I was undiagnosed for years and had symptoms that are similar to quite a few of those that you mentioned-the rash on the legs, bad acne like rash on face (from unknowingly eating large amounts of gluten) also had Epstein barr virus exposure which I've been told can go hand in hand with celiac disease. Also experienced bouts of depression and anxiety throughout most of my younger years. They say that 97% of the people who have it are undiagnosed. Just a simple blood test -tTGA for celiac, other tests for gluten intolerance-I hope you're feeling better and making progress!
