Have you tried anything for your stress levels? If that's what's the base cause of this, why not see if your doctor can help you treat the cause rather than the symptoms? I have IBS/D caused by anxiety and stress and when my doctor kept ignoring me, I went to a naturopath. I'm on a natural anxiety reducer now and it's working really well for me. I feel A LOT better. I'm not cured, but I feel like I'm finally heading down the right path. I'm not saying it's the right solution for everyone, I'm just finding it was the right solution for me. You're right, you can't just turn off the way you think and feel. I find my boyfriend says stuff like that when he gets frustrated with it. It's horrible the way this disease affects so many people and their families. Maybe you could encourage him to get a bit proactive with you and buy a yoga DVD and relax at home together? Some stress reduction for both of you may help, and getting him involved may help him understand more. Best of luck you!
