Not a great hobby, but I collect autoimmune diseases. Considering the c-Diff bacteria, did your doctor mention repopulating your GI tract (probiotics can help, or poo-transplants [ick]). Just wiping out the bacteria without replacing with "good" bacteria can be hard. Hopefully you can get the colitis under control soon, without the Budesonide. Keeping a food log to see if there are any triggers can be useful. RA is a nasty disease; I hope that is also well controlled. Hard to escape health problems and the stress that exacerbates them.
