Dealing with Chronic Illness Symptoms

I’ve been very frustrated lately with my chronic illness symptoms. I’ve been taking various medications to help calm some of the symptoms but I believe that I’m coming down with SIBO again which is counteracting my medications to some degree. I take a medication for my IBS-D to help with diarrhea and now I’m having diarrhea again. I take Gas-X for gas and now I’m going back into burping fits and various other unpleasant symptoms. It’s gotten to the point where I’m scared to eat anything since I don’t want to have to go to the bathroom or feel nauseous or end up having worse reflux symptoms and go into burping fits/struggle with flatulence. Is there any way that you guys cope with these symptoms? Any suggestions as to what I can do?
