Sorry you are feeling badly. Ask for a CT scan. My Mom had similar issues and the colonoscopy did not show anything. The scan did and it was easily corrected.
Is it possible that gluten might be the culprit? A former co-worker had lots of difficulties until she was diagnosed with that. I can't remember the medical term for it -- anyway, a gluten-free diet supposedly made all the difference!
ETA: The term I was looking for is "celiac disease." An article I found said persons with IBS are 4 times as likely to have gluten intolerance as non-IBS-sufferers. Irritable Bowel Syndrome Could Be Tied to Gluten Issues
I also am sorry to hear you have been feeling unwell and having a rough time... but, yes, maybe just wait and see if you can get things under control/back to feeling like yourself again before you stress about what to do wrt showing, etc. Would be a shame if you changed a contract only to find you were able to control your symptoms with diet/whatnot and really wanted to get back to it... baby steps, baby steps... ((((((hugs))))))) xoxoxI'm sorry you're not feeling well. If the doctor can get your health under control, maybe you can just put the shows on hold for a bit. You can still practice when you are feeling well.
